Recessed LED Troffer Kit

The Acuity Lithonia 2GTL2 LP840 is a 2 ft x 2 ft recessed LED troffer kit designed for commercial drop-ceiling installations. It delivers 3,700 lumens at 4000K with an efficacy of 98 lm/W from a 40 W integrated LED array. The fixture operates on 120 to 277V AC and carries DesignLights Consortium 5.0 certification.

Suited for General Commercial Lighting

This kit suits facility managers upgrading fluorescent U-bend T8 troffers to LED without rewiring ballasts. The flat lens and 80 CRI provide neutral white light for offices, corridors and retail floors. Buyers needing emergency battery backup, integrated occupancy sensors or a colour temperature other than 4000K should look at other models.

40 Watt Integrated LED Output

The 40 W integrated LED engine produces 3,700 lumens at 98 lm/W, fixing the light output and energy draw for the project. No ballast is required and the driver is dimmable for further control. This single power-and-lumen combination determines whether the fixture meets the required foot-candle levels for the space.
