Highlighted Features

Back-Lit Technology
Uses back-lit LED technology with a PMMA lens — no longer limited by light guide plate (LGP) constraints. Delivers high uniformity and excellent efficiency with significantly reduced subsequent maintenance costs.
High Efficiency
Achieves up to 123 lm/W efficacy with a CRI of 80. The 2×4 model operates at 50W, 40W, or 30W (selectable via dipswitch), producing up to 6,320 lm (CW/NW) or 4,526 lm (WW) at highest power.
Slim 36mm Profile
Only 36mm thick with the driver mounted on the side frame, keeping the panel flush and low-profile within the T-bar grid. Overall panel dimensions are 604×1214mm with a driver box offset of 375mm.
Three-Power Dipswitch
A built-in dipswitch on the driver allows selection between three wattage settings — 50W, 40W, and 30W — without rewiring. Provides flexibility to balance light output and energy consumption per space.
0–10V Dimming + DALI Option
Standard 0–10V dimming from 10% to 100% is included. A Digital Addressable Lighting Interface (DALI) driver option is also available for projects requiring advanced lighting control integration.
50,000-Hour Lifespan
Both the LED module and driver are designed for 50,000 hours of operation (L70B50). The optical module is sealed for life and requires no internal cleaning, minimizing long-term maintenance requirements.
CCT Options
Available in 3500K, 4000K, and 5000K colour temperatures with an SDCM of 6 and a UGR of 22. A 120° beam angle and Lambertian polar distribution ensure wide, comfortable coverage across the workspace below.
Wide Input Voltage
Accepts 100–347Vac at 50/60Hz, making it compatible with standard North American electrical infrastructure. Power factor of 0.95 and THD below 20% ensure clean, efficient power draw.
Material & Construction
Lens is PMMA, frame is aluminium (RAL 9010 white), and the back cover housing is a white-painted iron plate. IP40 rated, IK02 impact resistance, with SELV isolated driver tested at 3750Vdc/5mA/60S.
Easy T-Bar Installation
Designed for exposed T-bar grid ceilings as the default installation method (Manual: 92301). Wire suspension is also supported (Manual: 92203) using accessory kit PJB.DJ002-3 (2×4).
Application Environments
Suited for offices, retail stores, workshops, and schools. The combination of high efficiency, dimmability, and long lifespan makes it a practical choice for any commercial space requiring reliable, uniform overhead lighting.
