WAC Lighting R4FSAL-927-BK – Frequently Asked Questions
1) Does the WAC Lighting R4FSA 4in square trim come with the LED light engine, or do I need to order that separately?
The light engine ships with the R4FSA trim. The LED module is mounted to the trim on springs, so it can be pulled and replaced later without taking the trim out of the ceiling. It runs off a universal driver, so you are ordering the trim plus engine as one assembly and pairing it with the FQ recessed housing.
2) What housing does the R4FSA square trim fit?
It is built for the WAC Lighting FQ Recessed housing series in the 4 inch square size. The trim is part of the FQ collection, so pair it with an FQ 4in housing; it is not a universal retrofit trim for other manufacturers' cans.
3) Can I use this square adjustable trim in a bathroom or covered exterior soffit?
Damp locations are covered. The R4FSA is ETL and cETL rated for damp use, which takes care of enclosed showers outside the spray zone, bathrooms generally, and covered porches or soffits. It is not rated wet, so do not use it where it will see direct water. Operating range is -4F to 104F.
4) How far does the WAC R4FSA aim, and can I use it to wall wash?
Aiming runs 0 to 45 degrees of vertical tilt and 365 degrees of horizontal rotation, and center beam alignment is held through the whole adjustment range so the square aperture stays square to the ceiling as you aim. With 30 degree shielding it is a reasonable choice for floor-to-ceiling wall washing and accent work without dumping glare into sightlines.
5) Will the R4FSA work on a 277V commercial circuit?
Yes. Voltage is 120-240-277, so the same trim and light engine run on residential 120V, 240V, or a 277V commercial branch circuit. It is a hardwired fixture, not a plug-in, so it needs to be wired to the FQ housing and driver.
6) What dimmers work with the WAC FQ R4FSA LED trim?
It accepts 0-10V, ELV, and TRIAC dimming. On a commercial job that usually means 0-10V tied to the building control system; on residential remodels an ELV or TRIAC wall dimmer is the simpler route. Standard incandescent-only dimmers are not on the list, so match the dimmer to one of those three protocols.
7) What color temperatures and finishes does the R4FSA square trim come in?
Color temperature choices are 2700K, 3000K, 3500K, 4000K, and a 3000-1800K warm-dim option that drops toward candlelight as you dim. Finishes are Black, Dark Bronze, Haze, and White, plus a Haze/White two-tone on certain builds. If you are standardizing a building, pick one CCT and one finish and carry it across every opening.
8) Is the R4FSA good enough color quality for retail and hospitality spec work?
Rated 90 CRI, which is the usual floor for retail merchandising, gallery, and hospitality spec work where skin tones and fabric color have to read correctly. Average rated life is 50,000 hours, and the module is field-replaceable on its spring mounts if a unit fails in a ceiling you do not want to tear apart.
9) Does the WAC R4FSA meet California Title 24 for a new build?
It is listed as Title 24 and Title 20 compliant and Energy Star certified, which is what a California permit set is looking for on recessed fixtures. It also carries ETL and cETL marks, so it clears inspection on both US and Canadian jobs.
10) Square trim or round trim for a recessed job like this?
The R4FSA is a 4 inch square aperture, which is the choice when the ceiling detail is modern and you want the aperture to read as an architectural cut rather than a downlight hole. Round trims blend into older or transitional ceilings with less visual weight. Once you commit to square, every opening on that ceiling run should be square, since mixing the two in one field is the most common thing that gets flagged on walkthrough.
11) Will a painted white trim hold up in a high-humidity bathroom ceiling?
The trim body is two-piece die-cast aluminum rather than steel or plastic, so it is dimensionally stable and will not rust out in a damp bathroom ceiling. White, Black, Dark Bronze, and Haze finishes are all on the same aluminum casting.
