RAB WFD4 4 in Regressed Smooth Trim Deep Regress Wafer Downlight — 13W / Selectable CCT / 120V / White

The RAB WFD4 is a 4 in round deep regress wafer downlight in white finish with a regressed smooth trim, delivering up to 1,331 lumens at 13W with a 90° beam angle and 90 CRI. The deep regress profile replicates the look of a traditional recessed downlight without the need for a standard housing — the remote aluminum driver/junction box mounts directly to the structure or new construction mounting frame. CCT is field-selectable between five color temperatures via integrated dipswitch, with TRIAC/ELV dimming at 120V. Pairs with the HAD6/D10 driver (sold separately) for 120-277V universal voltage operation.

Construction & Design

The WFD4 features a metal enclosure in white finish with a regressed smooth trim and a polycarbonate light diffuser for even, smooth illumination. The remote aluminum driver/J-box uses keyhole mounting slots for direct mounting to the building structure or new construction mounting frame. Cutout size: 4-5/16 in. Weight: 0.7 lbs.

Performance, Control & Dimming

With efficacy up to 113 lm/W (4000K), 90 CRI, R9 ≥ 50, and a 90° beam angle, the WFD4 delivers focused, high-efficiency downward illumination. Rated lifespan: 50,000 hours L70 per IES LM-70. Flicker: 5%. Color consistency: 4-step MacAdam Ellipse; CCT warranted to shift no more than 200K over five years. Compatible with TRIAC/ELV dimming systems at 120V (dimmable to 10%). CCT field-adjustable via dipswitch at installation. Compatible with DRI-EMB-15S-LV 2-in-1 Driver + Battery Backup (sold separately) for emergency lighting.
