IP Rating Guide for Harsh Environments
Understanding ingress protection (IP) ratings is critical when selecting fixtures for industrial environments. The IP code uses two digits: the first rates solid particle protection (0–6), the second rates liquid ingress protection (0–9). Here’s what matters for industrial lighting:
| IP Rating | Solid Protection | Liquid Protection | Suitable For | Not Suitable For |
|---|---|---|---|---|
| IP65 | Dust-tight | Water jets (6.3mm nozzle) | Warehouses, covered parking, general industrial | Washdown areas, food processing, car washes |
| IP66 | Dust-tight | Powerful water jets (12.5mm nozzle) | Food processing, car washes, commercial kitchens, cold storage, outdoor covered | Continuous submersion |
| IP67 | Dust-tight | Immersion up to 1m | Temporary flood-prone areas | Most industrial lighting (overkill; costs more without added benefit) |
| IP69K | Dust-tight | High-pressure, high-temperature jets | Pharmaceutical cleanrooms, extreme washdown | Standard applications (significant cost premium) |
Installation Guide
Kingseng tri-proof lights support three mounting methods. All use the same stainless steel clip system — no drilling, no specialty tools, and no rewiring between methods.
1. Surface Mount
- Mark clip positions on ceiling or wall at the specified spacing (see datasheet for your model length).
- Secure stainless steel clips using appropriate anchors (M4 screws, not included — varies by substrate).
- Snap the fixture body into the clips. An audible click confirms proper seating.
- Connect power via the IP66-rated gland or end-cap connector.
2. Suspended Mount
- Replace surface-mount clips with suspended-mount clips (included accessory kit).
- Thread suspension cables or chains through the clip eyelets.
- Adjust height to application requirements. Standard cable kit supports drops up to 3 meters.
- Recommended for high-bay areas, open ceilings, and applications requiring adjustable light levels.
3. Linked (Continuous Row)
- Mount the first fixture using the surface or suspended method above.
- Connect the linking cable (included) from the first fixture’s output port to the second fixture’s input port.
- Snap the second fixture into its mounting clips.
- Repeat for up to 10 fixtures in a single run. End caps seal unused ports.
- Power is supplied to the first fixture only; all downstream fixtures are powered through the link cables.
Important: Maximum linked run is 10 fixtures for 20W–30W models and 8 fixtures for 40W–60W models. Exceeding the maximum linked load may cause voltage drop and uneven brightness. For longer runs, split into multiple circuits.
