2 ft LED Recessed Troffer

The Acuity Lithonia 2FSL2 33L EZ1 LP840 is a 2 ft by 2 ft LED recessed troffer designed for commercial drop-ceiling installations. It delivers 3,412 lumens at 4,000 K with an 82 CRI, making it suitable for offices, schools and retail spaces that need efficient general lighting.

Integrated LED — no lamp change required

The fixture uses an integrated LED array with no separate bulb to replace, so installation is limited to mounting the housing and wiring the driver. No ballast is needed and the unit operates on 120 to 277 V AC. The integrated design means the light engine cannot be swapped in the field; any failure requires full fixture replacement.

Verify voltage, dimming

Confirm the supply voltage falls within the 120 to 277 V AC range and that the existing dimming controls are compatible with the driver. The troffer fits a standard 2 ft by 2 ft grid opening; check the plenum depth and T-bar spacing to ensure the housing clears obstructions. This model includes no emergency battery backup.
