RAB DSK34-4R12940120WS – Frequently Asked Questions

1) Can the RAB DSK34 4-inch LED disk light be installed without a recessed can?
Yes. The DSK34 is a surface/flush mount disk light, so it mounts directly to the ceiling or into an existing recessed housing. That makes it the usual pick for retrofit work where there is no can in place, or where the ceiling cavity is too shallow for a housing. Fixture depth is 1.18 inches, so it sits close to the ceiling when surface mounted.
2) What color temperatures and finishes can I order the RAB DSK34 4-inch disk light in?
Two color temperatures, 3000K and 4000K, both at 90 CRI, and four trim finishes: white, black, bronze, and brushed nickel. Every combination is orderable, so a 4000K in bronze (DSK34-4R12940120BRS) and a 3000K in white (DSK34-4R12930120WS) both exist. For a property manager matching existing fixtures, 3000K reads warm like the incandescent it replaces and 4000K reads neutral white.
3) Will the RAB DSK34 run on a 277V circuit?
No. The DSK34 is a 120V only fixture. For 277V lighting branch circuits, common in commercial and institutional buildings, you need a 120-277V universal voltage disk or downlight instead. Putting this one on 277V will destroy the driver.
4) Is the RAB DSK34 12W LED disk light dimmable, and what dimmers work with it?
The DSK34 runs on a constant current driver at 120V. RAB publishes a dimmer compatibility list for the DSK34 (disk34_compatibility.pdf), and that document is what decides which specific dimmers pair with it. Check the model of dimmer you plan to use against that list before you standardize a building on it, because LED disk drivers are selective about trailing edge versus leading edge controls.
5) Is the RAB DSK34 low flicker enough for offices and classrooms?
Flicker is rated under 30 percent on the DSK34. That is the spec to point at when a school or healthcare client raises flicker sensitivity, headaches, or camera banding in a video conference room. Low flicker plus the constant current driver is why this fixture turns up in classroom and office retrofits rather than just closets and hallways.
6) How often will I have to relamp RAB DSK34 disk lights in a multi-family building?
You will not relamp them at all. The DSK34 is an integrated LED fixture rated for 50,000 hours, so there is no lamp to change. At 12 hours a day in a corridor that is roughly 11 years of service before the fixture itself is due. For an MRO budget, the trade is a fixture replacement every decade or so instead of a lamp change every year.
7) Can I use the RAB DSK34 in a wet location like a covered patio or a shower?
Stick to dry and indoor applications with the DSK34. It is built for interior residential and commercial spaces, offices, retail, healthcare, education, and hospitality. For a shower trim, a soffit, or anything exposed to weather, order a fixture with a wet or damp location rating on its own spec.
8) What is the difference between the 3000K and 4000K RAB DSK34 when I am matching existing lights in a building?
Same 12W fixture, same 90 CRI, same 4-inch round body; the only difference is the light color. Order 3000K (DSK34-4R12930120BNS in brushed nickel, for example) to match warm white incandescent or halogen already in apartments and lobbies. Order 4000K (DSK34-4R12940120BNS) to match neutral white fluorescent troffers or newer LED in offices, corridors, and back of house. Mixing the two in one sightline is obvious to anyone looking up, so pick one per space and stay with it.
9) Is 90 CRI worth paying for on a disk light, or is standard 80 CRI fine?
All DSK34 variants are 90 CRI, so there is no 80 CRI version to choose. Where 90 CRI earns its place is anywhere color judgment happens: exam and treatment rooms, retail displays where merchandise color has to read true, paint and finish inspection, and hospitality spaces where skin tones matter. In a back-of-house storage room or a mechanical space, the higher CRI buys you nothing you can see.
