RAB DSKFA-4R109CCT120WS/PIR – Frequently Asked Questions

1) Does the RAB DSKFA downlight have a built-in occupancy sensor?
Both sizes carry the /PIR suffix in the part number, so they ship with an integral passive infrared sensor: the 4 inch is DSKFA-4R109CCT120WS/PIR and the 6 inch is DSKFA-6R159CCT120WS/PIR. That matters if you're spec'ing for corridors, restrooms, storage rooms or anywhere a code-required occupancy control would otherwise be a separate wall device. If you want a plain switched downlight with no sensor, this is not the part.
2) What ceiling opening do I need for the RAB DSKFA flush mount downlight?
It comes in 4 inch and 6 inch round versions, so match the version to the aperture you already have. On a retrofit of existing cans, order the size that matches the can diameter, not the trim ring diameter. Wattage tracks the size: the 4 inch is the 10W unit and the 6 inch is the 15W.
3) Can I change the color temperature after these are installed in the ceiling?
Yes, CCT is field adjustable on the DSKFA downlight, so you set it at install rather than ordering a fixed 3000K or 4000K part. For a property manager that means one part number covers a whole building and you can match warmer lobby lighting to cooler back-of-house from the same box. It also kills the problem of a replacement fixture landing at the wrong color next to the existing run.
4) Will the RAB DSKFA downlight run on 277V in a commercial building?
No. This is a 120V fixture only. On a 277V lighting branch circuit, common in commercial and institutional buildings, you'd need either a different 120/277V universal-voltage downlight or a step-down transformer. Check the panel schedule before you commit to a quantity.
5) Is 60 lumens per watt enough for an office or retail space?
Efficacy on the DSKFA is rated at 60, which is modest for LED downlighting. It's workable for general ambient light in offices, hospitality and corridors, but if your project is chasing an energy code compliance number or a utility rebate that sets a minimum lumens-per-watt threshold, run the math against that threshold before you commit. For straight fixture-for-fixture replacement of older recessed cans it's a large step up.
6) Is this RAB downlight suitable for a healthcare or education facility where flicker is a concern?
Flicker is rated at 30 or less, which is why it gets called out for spaces with long occupancy: patient rooms, classrooms, offices. That's the spec to quote if a facilities group or a designer asks about visual comfort. Driver is constant current, so light output holds steady rather than drifting with load.
7) How often will maintenance have to get a ladder out for these?
Rated lamp life is 50,000 hours on the LED source. At roughly 12 hours a day that's over eleven years of service, which is the argument for standardizing a portfolio on one downlight rather than chasing lamp replacements. There is no separate lamp to change, the LED is integral to the fixture.
8) What finish is the RAB DSKFA trim, and will it match the other downlights in my ceiling?
The trim is white, both sizes. That matches standard white acoustical tile and painted gypsum ceilings and is the same finish most existing commercial downlight trims use. If your building is standardized on brushed nickel or black trims, this will read as a mismatch in the same room.
