RAB WFRL4S99FA120BS 4 in Square Smooth Edge-Lit Wafer Downlight — 9W / Selectable CCT / 120V / Black The RAB WFRL4S99FA120BS is a 4 in square edge-lit wafer downlight in black finish with a smooth trim, delivering up to 794 lumens at 9W with a 110° beam angle and 90 CRI. The edge-lit design produces smooth, uniform light distribution with a super slim profile — no recessed housing or junction box required. UV resistant polycarbonate construction with spring-loaded retention clips ensures fast, secure installation in new construction or retrofit applications. CCT is field-selectable between five color temperatures via integrated dipswitch, with TRIAC/ELV dimming at 120V.
