DLC Premium and ENERGY STAR Compliance: A Specifier Guide to LED Lighting Certifications
- ENERGY STAR Certification
- DLC (DesignLights Consortium) Premium
- UL Listing (Safety Certification)
- CE & UKCA (European & UK Markets)
- RoHS & REACH Compliance
- LEED v5 and WELL v2 Contribution
💡 Key Takeaway:
Good lighting decisions start with understanding the basics. Every Kingseng product uses standard sockets, carries UL/ETL safety certification, and is backed by a 2-year warranty.
For B2B lighting buyers, navigating the landscape of energy efficiency certifications is essential for project compliance, utility rebate eligibility, and LEED / WELL building certification credit attainment. This guide maps the certification landscape relevant to Kingseng products and explains what each designation means for commercial specifiers.
💡
ENERGY STAR Certification
ENERGY STAR is the most widely recognized energy efficiency label in North America. For LED luminaires, it requires:
- Efficacy ≥ 80 lumens per watt (varies by product category)
- Lumen maintenance L70 ≥ 25,000 hours
- CRI ≥ 90 Ra (for most indoor categories)
- Power factor ≥ 0.7 (residential) or ≥ 0.9 (commercial)
- Warranty ≥ 3 years (5 years for some categories)
Kingseng’s KS-PL pendant series (KS-PL-001 to KS-PL-013) and KS-WS wall sconce series (KS-WS-001 to KS-WS-009) meet or exceed ENERGY STAR criteria, with efficacy of 90–110 lm/W and L70 > 50,000 hours across the range.
DLC (DesignLights Consortium) Premium
DLC certification is the standard for commercial LED products in the United States and Canada. DLC Premium — the higher tier — qualifies products for utility rebate programs that can offset 30–50% of project fixture cost.
| Requirement | DLC Standard | DLC Premium | Kingseng Typical |
|---|---|---|---|
| Minimum efficacy | 90 lm/W | 110 lm/W | 95–120 lm/W ✅ |
| Minimum CRI | Ra ≥ 80 | Ra ≥ 90 | Ra ≥ 90 ✅ |
| Power factor (commercial) | ≥ 0.9 | ≥ 0.9 | ≥ 0.95 ✅ |
| L70 lifetime | ≥ 50,000 h | ≥ 50,000 h | ≥ 60,000 h ✅ |
| Warranty | ≥ 5 years | ≥ 5 years | 5 years ✅ |
| Dimmable | Not required | Required for many categories | 0–10V standard ✅ |
Currently, Kingseng KS-LT track lights carry DLC Premium listing, making them eligible for major utility rebate programs including NYSERDA, ComEd, PG&E, and Southern California Edison. DLC listings for pendant and wall sconce families are in progress — contact our sales team for current certification status.
UL Listing (Safety Certification)
UL 1598 (luminaire safety) and UL 8750 (LED components) are mandatory for commercial installations in the United States. Key elements of UL certification that Kingseng addresses:
- UL 1598 Wet/Damp Location: Our KS-AL alabaster series (KS-AL-001 to KS-AL-007) is UL-listed for damp locations — suitable for hotel bathrooms, covered patios, and poolside areas.
- UL 1993 (Self-Ballasted Lamps): Kingseng LED filament bulbs meet UL 1993 for screw-base retrofit applications.
- UL 2108 (Low Voltage Lighting Systems): Our 12V/24V accessory line and T8 wiring harnesses comply with UL 2108 safety standards.
CE & UKCA (European & UK Markets)
For European Union and United Kingdom installations, Kingseng products carry CE marking and UKCA certification, encompassing:
- EN 60598: Luminaire safety (equivalent to UL 1598)
- EN 55015: Electromagnetic emissions
- EN 61547: Electromagnetic immunity (includes flicker testing per IEEE 1789)
- EN 62493: Human exposure to electromagnetic fields from lighting equipment
- ErP Directive (EU) 2019/2020: Energy efficiency eco-design requirements
RoHS & REACH Compliance
All Kingseng products are RoHS (Restriction of Hazardous Substances) compliant — no lead, mercury, cadmium, or other restricted substances in excess of allowable thresholds. Our supply chain also meets REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) requirements for the European market, with full material declaration reports available for project submittal.
LEED v5 and WELL v2 Contribution
Specifying certified Kingseng products contributes to several credits under green building rating systems:
| Rating System | Credit | How Kingseng Products Help |
|---|---|---|
| LEED v5 | EA Prerequisite 1 (Energy Performance) | DLC Premium fixtures reduce LPD below ASHRAE 90.1 baseline |
| LEED v5 | EQ Credit (Indoor Environmental Quality) | CRI ≥ 90 and 3000K CCT support visual comfort; flicker-free drivers per IEEE 1789 |
| WELL v2 | Light Concept L02 (Circadian Lighting Design) | Tunable white and 0–10V dimmable fixtures support melanopic ratio targets |
| WELL v2 | Light Concept L04 (Glare Control) | COB optics in KS-LT track lights achieve UGR < 19 |
Certification Verification Checklist
- ☐ Verify DLC Premium listing (QLD number) for applicable product
- ☐ Confirm UL 1598 listing for the specific fixture and location type
- ☐ Request CE Declaration of Conformity for EU project specifications
- ☐ Check utility rebate eligibility via the DLC QPL database
- ☐ Request material declaration reports for LEED v5 Materials & Resources credits

Common Certification Mistakes (and How to Avoid Them)
| Common Mistake | The Fix |
|---|---|
| Specifying DLC Standard when Premium is required — Utility rebate programs increasingly require Premium-tier products for maximum incentives. | Check your utility’s TRM. Default to DLC Premium for maximum rebate eligibility. Kingseng’s KS-LT-22W carries DLC Premium listing. |
| Assuming ENERGY STAR covers commercial projects — Installing ENERGY STAR products in a commercial new-build and expecting utility rebates. | ENERGY STAR applies to residential rebates. For commercial, you need DLC. For residential ceiling fans, the KS-5212 carries ENERGY STAR. |
| Using CE marking as a substitute for NRTL listing — Specifying CE-marked fixtures for a US installation. | CE is not accepted by US electrical inspectors. You need UL, ETL, CSA, or TUV. All Kingseng North America products carry ETL certification. |
| Not checking DLC listing status at time of purchase — A product was DLC-listed during design but expired before procurement. | Always re-verify QPL status within 30 days of purchase order. Compare2Best tracks certification changes across manufacturers. |
