48L ADP EZ1 LP840 LED Troffer

The LITHONIA LIGHTING 2BLT4R 48L ADP EZ1 LP840 is a 2 ft x 4 ft LED recessed troffer designed for commercial drop-ceiling installations. It delivers 5,234 lumens at 4,000 K with an 82 CRI and operates at a maximum of 38 W. The integrated LED array removes the need for separate lamps or a ballast, and the fixture carries DLC 5.0 Premium certification.

Suited for standard grid ceilings.

This troffer suits facility managers upgrading fluorescent T8 layouts to LED with minimal rewiring, as it runs on 120–277 V AC and supports dimming. It is not for projects that require an integrated occupancy sensor, photocell or emergency battery backup, since none are included. Buyers needing a surface-mount or suspended fixture should look at a different form factor.

38 W maximum fixture wattage decides fit

The single specification that determines whether this part fits the job is the 38 W maximum fixture wattage. It sets the power draw per unit for circuit loading, energy-code compliance and DLC qualification. If the lighting plan allows a higher or lower wattage density, a different troffer must be selected.
