WAC Lighting R4FBFT-1 – Frequently Asked Questions
1) Can the WAC Lighting R4FBF 4 inch frame-in housing be installed in direct contact with insulation?
No. The R4FBF is Non-IC rated, so insulation has to be held back from the housing. It is also rated for Dry locations only, which rules out showers, soffits, and covered exteriors. If your ceiling cavity is insulated or the location is damp, this is the wrong housing for the opening.
2) Does one R4FBF housing work for both round and square FQ trims?
Yes. The FQ series uses a single housing size and one uniform ceiling cutout that supports round or square, trimmed or trimless luminaires, including downlight (DL), adjustable (ADJ), and wall wash (WW) configurations. For a contractor that means you can rough in every opening with the same frame-in kit and decide the trim style later.
3) What voltage can the WAC FQ R4FBF housing run on, and will it work on a 277V commercial circuit?
The R4FBF driver accepts 120, 240, and 277 volts, so the same housing works on a residential 120V branch circuit and on a 277V commercial lighting circuit. It is a hardwired fixture, not cord-and-plug.
4) What is the difference between the R4FBFT and the R4FBFT-EM?
The -EM suffix is the emergency version, which adds emergency backup operation to the same 4 inch FQ frame-in housing. Both are offered in 13W, 19W, 25W, and 28W. Spec the -EM only on the openings your egress lighting plan calls for; the standard R4FBFT covers everything else.
5) Does the WAC R4FBF housing come with the light source, or do I order the trim separately?
No lamp or bulb is included with the housing. The R4FBF is the frame-in half of the assembly; the FQ luminaire and trim, round or square, trim or trimless, DL, ADJ, or WW, is ordered separately. Plan both lines on your takeoff.
6) What dimmers work with the WAC FQ 4 inch recessed housing?
The driver is compatible with 0-10V, ELV, and TRIAC dimming. On a 277V commercial job that generally means 0-10V control; on 120V residential work ELV or TRIAC wall dimmers apply. Match the dimmer type to the control scheme you are running before you order.
7) What wattages does the WAC R4FBF 4 inch housing come in?
Four output levels are offered: 13W, 19W, 25W, and 28W, each available in the standard R4FBFT and the emergency R4FBFT-EM. Higher wattage gives more lumen output for high ceilings or open commercial spaces; the 13W is the usual pick for residential ceilings at standard height.
8) Is the R4FBF only for new construction, or can it go into an existing ceiling?
It is a frame-in new construction housing, which means it mounts to the joists or bar hangers with the ceiling open. It is also used on renovation work where the ceiling is being opened up or drywall is going back in. For a finished ceiling you cannot get above, a frame-in housing is not the right choice.
9) What happens if the driver on the FQ recessed housing fails after install?
The driver uses quick connectors, so it can be swapped out without cutting or rewiring the branch circuit connections. That matters for facility maintenance crews who need to service a fixture from below without pulling the housing.
10) What is the WAC R4FBF housing made of?
20 gauge galvanized steel. The galvanizing resists corrosion in a plenum or an unconditioned attic space, and 20 gauge is stiff enough to hold alignment while drywall is hung around the frame-in.
