WAC Lighting R4FRNL-1 – Frequently Asked Questions
1) Can the WAC FQ R4FN 4" housing be installed in a ceiling where insulation touches the fixture?
No. The FQ 4" new construction housing is Non-IC rated, so insulation has to be kept clear of the housing body. In an insulated attic or a sealed ceiling cavity you need to maintain the clearance called for by the manufacturer or choose an IC-rated housing instead. It is also rated for Dry locations only, so no showers, soffits or covered exteriors.
2) Do I need a different FQ housing for round trims versus square or trimless trims?
No, one housing covers all of them. The 4" FQ housing accepts the full line of round and square FQ trims in both trimmed and trimless configurations, which means you can set all the ceiling cutouts the same size and decide on trim style later. For stocking, that is one housing part number instead of four.
3) Will the WAC FQ 4" recessed housing run on 277V in a commercial building?
Yes. The FQ 4" housing is a hardwired unit with 120-240-277V input, so the same part works on a 120V residential branch circuit and on a 277V commercial lighting circuit without ordering a voltage-specific version.
4) What dimmers work with the WAC FQ 4" LED recessed housing?
It accepts 0-10V, ELV, and TRIAC dimming. On a commercial job with a 0-10V control system you wire the low-voltage control leads to the driver; on residential work an ELV or TRIAC wall dimmer will do. Match the dimmer protocol to one of those three and verify the dimmer's load rating against the wattage you order.
5) What do I have to specify when ordering the R4FN FQ housing?
Two choices: the model, R4FRNL or R4FSNL, and the wattage, which comes in 13, 19, 25 and 28 watts. Both models are offered in all four wattages. The lamping is built in, so no bulbs are ordered separately, and trim is a separate line item since the housing ships without it.
6) If the driver fails after a few years, do I have to pull the housing out of the ceiling?
No. The FQ housing has quick connectors installed on the driver, so the driver pulls and swaps without tools and without disturbing the housing or the ceiling. That matters on a property with dozens of downlights where access above the ceiling is limited.
7) Is the WAC FQ 4" housing suitable for retrofitting into an existing ceiling?
It is a new construction housing, which means it mounts to joists or bar hangers from above before the ceiling is closed. For an existing finished ceiling with no access from above you want a remodel-style housing instead, not this one.
8) Is the FQ 4" recessed housing listed for use on a permitted commercial project?
Yes, it carries ETL and cETL listings, so it is recognized for both US and Canadian installations, with a Dry location rating. The body is 20 gauge galvanized steel.
9) Can this FQ housing be used for emergency egress lighting?
There is a trimmed EM option in the FQ line for applications where code requires backup illumination. If your drawings call for emergency downlights in a corridor or stair, specify the EM version rather than the standard housing.
10) Will one housing type cover downlight, adjustable and wall wash locations on the same job?
Yes. The 4" FQ housing is sized so DL, ADJ and WW configurations all share the same ceiling cutout, so a floor plan mixing straight downlights, aimable accents and floor-to-ceiling wall wash runs off a single housing and a single hole size.
11) Is the WAC FQ 4" housing Energy Star certified?
No, the FQ 4" housing is not Energy Star certified. If a rebate program or utility incentive on your project requires Energy Star listed luminaires, this housing will not qualify on that basis.
