Product identity

The Acuity Lithonia 2GTL4 LP835 is a 39 W LED recessed troffer kit that delivers 4,000 lm at 3,500 K with a CRI of 82. It suits offices, schools and retail spaces that need efficient general lighting from a 2 ft x 4 ft flat-lens fixture.

Integration requirements

The unit operates on 120 to 277 V AC and requires no external ballast, simplifying installation in standard grid ceilings. Integrated LEDs remove the need for lamp stock and the DLC 5.0 Premium listing supports utility rebate programs where available.

Sustained operation

At 105 lm/W the fixture maintains efficacy during continuous duty without the lumen depreciation common to fluorescent alternatives. No emergency battery backup is included, so a separate egress solution is required for code compliance. Dimmable driver allows output reduction for further energy savings.
