WAC Lighting R4FRDL-927-BK – Frequently Asked Questions
1) Will the WAC Lighting R4FRD trim fit any 4 inch recessed can, or only WAC FQ housings?
The R4FRD is a 4 inch round trim built for standard 4 inch FQ Recessed housings from WAC Lighting. It is not a universal retrofit trim for generic 4 inch cans. Because the LED light engine ships mounted on the trim with springs, you still need the matching FQ housing and its driver arrangement to complete the install.
2) Can this 4 inch LED downlight trim go in a shower or a covered outdoor soffit?
Yes. The R4FRD carries an ETL and cETL Wet Location rating, so it is acceptable in showers, bathrooms and covered exterior areas such as soffits and porches. Operating range is -4F to 104F (-20C to 40C), which covers most covered outdoor conditions but not hard winter exposure below -4F.
3) What color temperatures does the R4FRD come in, and what is the 3000-1800 option?
Five choices: 2700K, 3000K, 3500K, 4000K, and a 3000-1800 warm dim option. The warm dim shifts from 3000K down toward 1800K as you dim it, the way an incandescent does, which is what people spec for restaurants, hospitality and residential living spaces. All five are offered in both trimmed and trimless styles.
4) Will this downlight work on the 0-10V dimming system already in my building?
Yes. The R4FRD is compatible with 0-10V, ELV and TRIAC dimming, so it drops onto a commercial 0-10V control system or a residential forward/reverse-phase dimmer. It is hardwired, and the driver takes universal 120-240-277V input, which is what lets the same trim go into a 277V commercial circuit and a 120V residential one.
5) Do I need a drywall mud ring for the trimless version of this WAC 4 inch downlight?
Trimless and trimmed are two separate orderable styles of the R4FRD. The trimless version is the one that finishes flush into the ceiling plane with no visible flange, so it is the choice when the drawing calls for a monolithic ceiling; the trimmed version lands a flange over the ceiling opening and is more forgiving of a rough cut. Pick the style at order time, since you cannot convert one into the other in the field.
6) Can I aim this recessed fixture to wash a wall or highlight artwork?
Yes. The R4FRD adjusts 45 degrees vertically and rotates 360 degrees horizontally, so it will wash a wall floor-to-ceiling or pick up art from a ceiling run. The 30 degree shielding angle keeps the source out of sight lines when it is tilted, and reflectors are supplied so you can change beam angle in the field. The trim also accepts one lens or glare-control accessory.
7) Do I have to order lamps separately for the WAC R4FRD?
No separate lamp is needed. The LED module comes with the trim, running on a universal driver, and it is rated for 50,000 hours average life. When the engine does eventually fail, it unclips from the trim on springs rather than requiring the housing to come out of the ceiling, which is the reason facilities crews like this series for high-ceiling and tenant spaces.
8) Does the R4FRD meet California Title 24 for a residential or commercial project?
Yes. The R4FRD is stated as Title 24 and Title 20 compliant and Energy Star certified, which is what gets it approved on California new construction and renovation submittals. Pair that with the wet location listing and it covers bath and exterior-covered locations on the same spec.
9) Is 90 CRI good enough for retail display and kitchen lighting?
At 90 CRI, the R4FRD renders merchandise, food and skin tones accurately enough for retail, hospitality and residential kitchens, and it is the threshold most commercial lighting specs call for. If your spec sheet demands 95+ or an R9 value, this is not the fixture.
10) What finishes are available on this WAC 4 inch round downlight trim?
Black, Dark Bronze, White and Haze. On the trimmed style the haze option is listed as Haze/White, meaning a haze cone with a white flange, while the trimless style carries a straight Haze. All finishes are on a two-piece die-cast aluminum body, so you can mix color temperature and finish across a job and keep the same trim profile.
