Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself.

(2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |

- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces.

(2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |

Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds). For commercial projects exceeding 500 units, extended 7-year warranty options are available. RMA claims are processed within 5 business days with replacement units shipped within 15 business days.” } } ] }Next Steps: Specify and Source with Confidence

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |
OEM/ODM Customization Options
Kingseng’s Shenzhen factory offers extensive customization for commercial step light and in-ground orders of 100+ units per SKU:
- Custom Bezel/Trim Finishes: Any RAL color powder coat on aluminum bezels. Electroplated finishes (polished chrome, satin brass, antique bronze, PVD gold) for stainless steel trims. Custom laser-engraved logo or pattern on bezel face.
- CCT and CRI Customization: Fixed or selectable CCT from 2200K (ultra-warm, candlelight effect) to 6500K (daylight). CRI 90+ and CRI 95+ LED arrays available for projects requiring premium color rendering, hotels, luxury retail, art installations.
- Beam Angle Customization: Custom optics for non-standard beam distributions. Elliptical beams for linear wall washing from in-ground positions. Asymmetric beams for step lights that need to illuminate the tread without spilling onto adjacent surfaces.
- Driver and Control Integration: 0-10V, DALI, DMX512, TRIAC, or Bluetooth Mesh drivers. Integrated microwave motion sensors for on-demand step illumination. Photocell integration for dusk-to-dawn in-ground uplighting.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).

Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.

They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).

KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).

Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.

They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |

Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds). For commercial projects exceeding 500 units, extended 7-year warranty options are available. RMA claims are processed within 5 business days with replacement units shipped within 15 business days.” } } ] }Next Steps: Specify and Source with Confidence

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.

Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion.

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic.

For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.

The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways

For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.

Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping.

Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing.

Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.

Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing.

Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|

Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |

- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds). For commercial projects exceeding 500 units, extended 7-year warranty options are available. RMA claims are processed within 5 business days with replacement units shipped within 15 business days.” } } ] }Next Steps: Specify and Source with Confidence

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic.

Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination.

The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds). For commercial projects exceeding 500 units, extended 7-year warranty options are available. RMA claims are processed within 5 business days with replacement units shipped within 15 business days.” } } ] }Next Steps: Specify and Source with Confidence

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes.

KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).

KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic.

Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).

For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.

- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds). For commercial projects exceeding 500 units, extended 7-year warranty options are available. RMA claims are processed within 5 business days with replacement units shipped within 15 business days.” } } ] }Next Steps: Specify and Source with Confidence

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells).

Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).

- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells).

Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |

Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic.

Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).

For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.

- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion.

Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic.

Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells).

Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |

They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate.

All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians.

Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).

For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways

For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.

Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping.

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |

Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |

Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Frequently Asked Questions
{ “@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [ { “@type”: “Question”, “name”: “What is the difference between recessed and surface-mount LED step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Recessed step lights mount inside the riser or wall cavity, sitting flush with the surface for a clean, architectural look. They require a cutout and sufficient mounting depth (40–55mm for Kingseng models). Surface-mount step lights attach directly onto the finished surface with no cavity required, ideal for concrete stairs where cutting is impractical, waterproof deck membranes that cannot be penetrated, or retrofit installations. Both types deliver equivalent illumination; the choice is primarily an installation and aesthetic decision.” } }, { “@type”: “Question”, “name”: “What IP rating do I need for outdoor step lights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “IP65 minimum for covered outdoor stairways (under eaves, within enclosed stairwells). IP67 is recommended for fully exposed outdoor stairs, pool surrounds, and any location where standing water may accumulate. IP65 protects against water jets from any direction; IP67 adds protection against temporary immersion, critical when rain pools against the fixture face on horizontal or near-horizontal surfaces. All Kingseng 6W–12W step lights are IP67 rated as standard.” } }, { “@type”: “Question”, “name”: “Can in-ground LED lights be driven over by vehicles?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard Kingseng in-ground fixtures are rated for 500kg static load (Class A/B per EN 124) — sufficient for pedestrian traffic, maintenance carts, and occasional light vehicle passage. For regular vehicular traffic (driveways, parking areas), specify the reinforced housing option with 1,500kg load rating (Class C). Even reinforced fixtures are designed for slow-speed, intermittent vehicle passage, not highway-speed or continuous heavy truck traffic. For roadway applications, contact Kingseng engineering for custom engineered solutions.” } }, { “@type”: “Question”, “name”: “How do I prevent water damage to in-ground LED uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Three layers of protection prevent water damage: (1) Install a 150–200mm gravel drainage layer beneath the fixture mounting sleeve to prevent standing water. (2) Use the included mounting sleeve with integrated weep holes, never install the fixture directly into soil or concrete without the sleeve. (3) Ensure all cable connections use IP68-rated junction boxes or gel-filled connectors, positioned above the expected water table. Kingseng in-ground fixtures also include a pressure-compensating breathable membrane that prevents internal condensation, a feature omitted on budget imports.” } }, { “@type”: “Question”, “name”: “What is the recommended spacing for LED step lights on commercial stairs?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “For standard commercial stairs (up to 1.2m/4ft width): one centered 3W fixture per riser provides 10–20 lux. For stairs 1.2m–2.0m wide: one centered 6W fixture. For stairs over 2.0m wide: two or more fixtures per riser, spaced evenly. Side-wall mounting: one fixture every 2–3 risers, staggered left and right, at 300–400mm above tread nosing. Always increase target illuminance by 25% for outdoor stairs due to lower surface reflectance of concrete and stone. Photometric verification is recommended for non-standard configurations.” } }, { “@type”: “Question”, “name”: “Are LED step lights required to meet ADA compliance?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “ADA standards do not mandate specific step lighting requirements for stairs (ADA governs accessible routes, which primarily use ramps). However, the ADA’s broad obligation to provide safe, hazard-free paths of travel, combined with IBC Section 1009 (minimum 1 footcandle on stair walking surfaces) and NFPA 101 (emergency egress illumination), effectively requires commercial stairways to have adequate lighting. High-contrast nosing strips paired with anti-glare LED step lights provide the most accessible solution for visually impaired pedestrians. Kingseng’s honeycomb louver and prismatic diffuser options ensure the light source itself is never directly visible, eliminating disabling glare.” } }, { “@type”: “Question”, “name”: “Can Kingseng customize step light and in-ground fixtures for my project?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Yes. Kingseng offers comprehensive OEM/ODM customization starting at 100 units per SKU. Options include custom RAL color powder coating, electroplated finishes (brass, chrome, PVD gold), custom CCT (2200K–6500K), CRI 90+ or 95+ LED arrays, non-standard beam angles, custom housing dimensions, private label packaging, and integration with any major control protocol (0-10V, DALI, DMX512, TRIAC, Bluetooth Mesh). Lead time is 30–45 business days for custom orders. Contact our engineering team with your specifications for a custom quotation.” } }, { “@type”: “Question”, “name”: “What is the warranty on Kingseng LED step lights and in-ground uplights?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “All Kingseng LED step lights and in-ground uplights carry a 5-year full replacement warranty. This covers manufacturing defects, LED lumen depreciation below L70 within the warranty period, and driver/power supply failure. The warranty is backed by LM-80 and TM-21 test data from our LED chip suppliers (primarily Seoul Semiconductor and Lumileds). For commercial projects exceeding 500 units, extended 7-year warranty options are available. RMA claims are processed within 5 business days with replacement units shipped within 15 business days.” } } ] }Next Steps: Specify and Source with Confidence

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- Gravel Drainage Layer: Excavate 150–200mm (6–8 inches) below the fixture mounting sleeve and fill with 20mm crushed gravel. This creates a drainage reservoir that prevents water pooling around the housing.
- Mounting Sleeve/Cannister: All Kingseng KS-IG models include a pre-formed mounting sleeve. Install the sleeve flush with the finished surface grade. The sleeve integrates weep holes at the base to allow water to drain into the gravel layer below.
- Concrete Encasement: In paved hardscape applications, pour the concrete surround with a 2–3% slope away from the fixture trim ring. This prevents water sheeting across the lens.
- Pressure-Compensating Membrane: Every Kingseng in-ground fixture includes a Gore-Tex-style breathable membrane vent. This equalizes internal pressure during temperature swings and prevents condensation buildup inside the sealed housing, a critical feature that budget fixtures omit.
- Cable Gland Sealing: All cable entries use IP68-rated compression glands with double O-ring seals. Never install in-ground fixtures with cable entries oriented upward; always route cables through the base or side entry points and ensure the gland is properly torqued (3.5 N·m for Kingseng standard glands).
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |

Request a Project Quotation
Contact Kingseng for a detailed project quotation including photometric layouts (IES files), sample availability, and current lead times. Specify your model requirements, quantities, CCT preferences, and any customization needs for an accurate FOB Shenzhen quotation within 24–48 hours.
Disclaimer: This guide is for informational purposes. Product specifications, pricing, and lead times are subject to change. Contact Kingseng for binding quotations, current availability, and project-specific technical documentation. All load ratings are based on in-house testing per EN 124 / AS 3996 standards. Always consult a licensed electrician and structural engineer for installation compliance with local building codes.
Housing Selection and Load Rating
In-ground fixtures installed in driveable surfaces, pathways, driveways, pool surrounds, and pedestrian plazas, must withstand static and dynamic loads from foot traffic, maintenance vehicles, and in some cases, light vehicular traffic. Kingseng in-ground fixtures are rated using the following classification:
| Load Class | Static Load | Dynamic Load | Typical Application | Kingseng Models |
|---|---|---|---|---|
| Class A (Pedestrian) | 500 kg (1,100 lbs) | 2,000 N | Landscape beds, gardens, planter surrounds | KS-IG3-RD, KS-IG3-SQ |
| Class B (Light Traffic) | 500 kg (1,100 lbs) | 5,000 N | Pathways, plazas, pool surrounds, patio decks | KS-IG6-RD, KS-IG6-SQ, KS-IG12-RD |
| Class C (Heavy Pedestrian) | 1,500 kg (3,300 lbs) | 10,000 N | Driveways, parking areas, loading zones (light vehicles only) | KS-IG18-RD, KS-IG24-RD, KS-IG36-RD (reinforced housing) |
Commercial Applications
Theater and Auditorium Steps
Performing arts venues require step lighting that balances safety with zero light spill onto the stage or performance area. Specify KS-SL3-R recessed step lights with 2700K warm white output at the lowest functional dimming level (5% via 0-10V). Install in alternating risers with 150mm setback from aisle edges to create a discreet guide path. Anti-glare louvers are non-negotiable, the audience must see only the illuminated tread, never the light source itself. For orchestra pit steps and backstage stairways, increase to 6W models with red or blue gel-filtered options for dark-adapted eye preservation.
Hotel and Hospitality Stairways
Hotel stairways serve dual functions: everyday guest circulation and emergency egress. Lighting must satisfy both with elegance and reliability. KS-SL6-R recessed step lights (6W, 3000K) provide 540 lumens per fixture, sufficient for 1.2m-wide stair runs with a single centered installation. Specify brushed nickel or dark bronze bezel finishes to coordinate with hospitality interior design palettes. For luxury properties, upgrade to KS-SL9-R (9W) or KS-SL12-R (12W) with stainless steel 316 trim for a premium architectural aesthetic. Connect step light circuits to the building’s central lighting control system (DALI or 0-10V) for scheduled dimming: 100% during daytime hours (safety priority), dimmed to 30% after 10 PM (ambiance priority).
Restaurant Decks and Outdoor Dining Terraces
Outdoor dining areas present step lighting challenges: fixtures must withstand rain, spilled liquids, cleaning chemicals, and heavy foot traffic while contributing to the restaurant’s ambiance. KS-SL6-S surface-mount step lights (IP67) installed on deck risers or perimeter walls deliver 540 lumens of warm 2700K or 3000K light that complements candlelit table settings. Surface-mount installation avoids cutting into waterproof deck membranes, a critical advantage for rooftop and elevated terraces where penetration of the waterproofing system creates costly liability. Pair deck step lights with KS-IG6-RD in-ground uplights (6W, 30° beam, 3000K) placed at the base of feature trees, pergola columns, or privacy screens to create layered outdoor lighting that extends dining hours into the evening. For more on this topic, read our guide: LED Garden and Landscape Lights for Commercial Projects:.
Landscape Uplighting
Commercial landscape uplighting transforms exterior spaces after dark. KS-IG12-RD in-ground uplights (12W, 15°–30° beam) installed at the base of specimen trees create dramatic canopy silhouettes, specify 3000K for warm, natural rendering of bark and foliage or RGBW for programmable color effects in hotel gardens, resort pools, and event venues. For architectural facade uplighting, KS-IG24-RD (24W, 30°–60° beam) washes columns, entrance portals, and signage with uniform illumination. Kingseng’s in-ground fixtures feature field-interchangeable optics: the beam angle can be changed on-site without replacing the entire fixture, a significant advantage during commissioning when photometric adjustments are needed.
Pathway Markers and Wayfinding
Commercial pathways through parks, campuses, and urban plazas benefit from low-level marker lighting that defines the path edge without the visual clutter of bollards. KS-IG3-RD in-ground markers (3W, 45° wide beam, 2700K or 3000K) installed flush with the walking surface at 3–5m (10–16 ft) intervals create a continuous illuminated guide. For projects requiring pathway lighting combined with step lighting, specify matching CCT and bezel finishes across both KS-IG and KS-SL product families. Square bezel models (KS-IG3-SQ) provide a clean architectural line that integrates with modern paver layouts.
Pool Surrounds and Wet Deck Areas
Pool surrounds demand the highest level of ingress protection and corrosion resistance. KS-SL6-R recessed step lights with IP67 rating installed in pool deck steps and perimeter walls provide safe illumination in a chemically aggressive environment (chlorine, salt, pH-adjusted water). Specify 316 stainless steel trim and hardware, never standard 304 or aluminum in pool environments, where accelerated corrosion causes fixture failure within 12–24 months. For in-pool deck uplighting, KS-IG6-RD (6W, IP67) installed in the surrounding hardscape illuminates water features, diving platforms, and poolside landscaping. Critical note: In-ground fixtures installed within 1.5m (5 ft) of the pool water’s edge must be low-voltage (12V DC) and connected to a GFCI-protected circuit per NEC 680. Kingseng offers 12V DC driver options for all in-ground models, specify at time of order.
IP67 Rating and Load Capacity Explained
Why IP67 Matters for Step and In-Ground Lights
IP67 represents the practical minimum for fixtures installed at or below ground level. Here’s why each protection level matters:
- IP65 (Dust-tight + Water Jets): Suitable for step lights in covered or semi-exposed locations, under building eaves, within covered stairwells, or on porches with roof overhangs. IP65 fixtures can withstand driving rain from any direction but are not designed for pooling water or ground contact.
- IP66 (Dust-tight + Powerful Water Jets): Suitable for fully exposed step lights on open stairways, uncovered decks, and coastal installations where salt spray and wind-driven rain are factors. IP66 provides an extra margin of protection over IP65.
- IP67 (Dust-tight + Temporary Immersion): The required standard for in-ground uplights and step lights in areas prone to standing water, pool surrounds, landscape beds with irrigation, pathways with poor drainage, and any fixture installed flush with or below grade. IP67 means the fixture can survive temporary immersion in 1 meter of water for 30 minutes without water ingress. All Kingseng in-ground fixtures and the KS-SL6/9/12 step light models are IP67 rated.
Important distinction: IP67 does not mean the fixture can operate underwater permanently. It means it can survive temporary submersion. For permanent underwater applications (fountains, reflecting pools, submerged pond lighting), IP68 with specified immersion depth and duration is required. Kingseng can provide IP68-rated custom versions of select in-ground models for submerged applications, contact our engineering team for specifications.
How Kingseng Achieves 500kg Load Capacity
The 500kg static load rating on Kingseng in-ground fixtures is not a marketing claim, it’s an engineered result validated through destructive testing. Four design elements make this possible: For more on this topic, read our guide: Outdoor LED Lighting for Commercial Projects: Facade, Landscape.
- Tempered Glass Lens (8–15mm thickness): Thermally tempered to EN 12150 standards, with compressive surface stress exceeding 10,000 psi. The lens alone supports the rated load, the housing provides stability and alignment. Lens thickness scales with fixture diameter: 8mm for 3W models (Ø60mm), 10mm for 6W (Ø90mm), 12mm for 12W (Ø120mm), and 15mm for 18W–36W models (Ø150–200mm).
- 316 Stainless Steel Housing and Trim Ring: Marine-grade stainless steel resists corrosion in chlorinated pool water, coastal salt spray, and de-icing chemical exposure. The housing wall thickness (2.5mm minimum) provides structural rigidity without deformation under load.
- Load-Distributing Mounting Sleeve: The pre-installed mounting sleeve transfers load from the trim ring through the sleeve walls into the surrounding concrete or compacted substrate. This prevents point-loading on the fixture body itself.
- Silicone Gasket Compression Seal: A continuous compression-molded silicone gasket between the lens and housing maintains the IP67 seal under load. Unlike EPDM or neoprene gaskets that can cold-flow and lose compression over time, silicone maintains its elastic properties across the fixture’s full operating temperature range (–40°C to +60°C).
Anti-Glare Design Options
Glare from step lights and in-ground uplights is both a safety hazard (disabling glare that impairs depth perception on stairs) and an aesthetic flaw (harsh visible light sources that detract from architectural design). Kingseng offers four anti-glare solutions across the step light and in-ground product lines:
| Anti-Glare Option | How It Works | Best For | Available On | Price Impact |
|---|---|---|---|---|
| Standard Louver | Linear blade louvers recessed 15mm behind lens plane. Blocks direct view of LED source above 45° viewing angle. | General commercial stairways, pathways, decks | All KS-SL models (standard) | Included at base price |
| Honeycomb Louver | Hex-cell grid (cell size 6mm) eliminates glare from all angles above 30°. Reduces lumen output by ~15%. | Theater aisles, luxury hospitality, high-end residential | KS-SL6-R, KS-SL9-R, KS-SL12-R | +$3.00/unit |
| Prismatic Diffuser | Micro-prismatic acrylic lens spreads light evenly across the tread while concealing the LED source completely. | Wide stairways, ADA-compliant installations requiring uniform tread illumination | All KS-SL models | +$2.00/unit |
| Deep-Set Recess (In-Ground) | LED array positioned 40–60mm below the lens plane with conical glare shield. Limits visible source to within 20° of vertical axis. | Landscape uplighting, facade illumination, any upward-facing in-ground fixture | KS-IG12-RD, KS-IG18-RD, KS-IG24-RD, KS-IG36-RD | +$5.00/unit |
