Wet location
LDRS Radius is the multi-fⒶMILY PRO ultra-slim downlight: an edge-lit panel 0.38 in deep that clips into the ceiling cut-out on its own remote J-box, with no housing needed. It also fits most 4 and 6 in housings. It comes in 4, 6 and 8 in, from 9 to 18 W, and is rated for wet locations and for closets under the NEC. Color temperature is a switch on the J-box and is not in the catalog number.
