RAB R3-9 – Frequently Asked Questions

1) What is the difference between the smooth and baffle trim on the RAB R3 Series?
Trim is the choice you make on the order, and it is purely optical, not electrical. Both 9W and 15W builds are offered either way: R3-9 and R3-15 are smooth trims, R3-9B and R3-15B are baffle. A baffle trim uses ridged rings inside the cone to cut glare, which is what most people want over seating, desks, and gallery walls; a smooth reflector pushes more light down and reads cleaner in a modern ceiling. Everything else about the two is the same, including the white finish.
2) Should I order the 9W or the 15W RAB R3?
Four builds exist and wattage is one of only two choices: 9W (R3-9, R3-9B) or 15W (R3-15, R3-15B). The 15W is the one to standardize on for general ceiling coverage in offices, retail floors, and corridors where you want fewer fixtures on wider spacing. The 9W suits closer spacing, lower ceilings, accent runs, and task or display lighting where the higher output would be too much. Both use the same LED platform and the same constant current driver, so mixing them in one space keeps a consistent look.
3) Does the RAB R3 need a separate driver or transformer?
No separate driver box is needed. The R3 is a constant current LED unit, so the driver is part of the product rather than something you source and mount on the plenum side. That matters for retrofit work in finished ceilings, where there is no room for a remote driver above the opening.
4) How long do the RAB R3 LEDs last before they need to be relamped?
Rated LED life is 50,000 hours. The LEDs are not a replaceable lamp, so at end of life the unit is swapped rather than relamped. For an MRO or property maintenance schedule, 50,000 hours works out to roughly 17 years at 8 hours a day, which is the argument for using these where ladder access or lift rental is the real cost of a lamp change: high ceilings, stairwells, and tenant spaces you would rather not enter.
5) What color is the RAB R3 trim, and will it match the other ceilings in my building?
All four builds come in white, in both smooth and baffle trim. There is no bronze, black, or brushed option on the R3, so if you are matching a ceiling that already runs white recessed trims you are consistent across the whole run, and if your existing trims are a dark finish these will not blend.
6) How much does one RAB R3 unit weigh and how big is the housing?
Each unit weighs 1.132 lb and the housing measures 6.06 by 5.59 by 3.78 inches. That weight is light enough that the fixture is not driving your ceiling support decision on a typical drywall or T-bar install, and the height figure is the number to check against your plenum depth before you commit to a large quantity.
7) What are the exact RAB part numbers for the R3 Series?
Four catalog numbers cover the series: R3-9 (9W smooth), R3-9B (9W baffle), R3-15 (15W smooth) and R3-15B (15W baffle). The trailing B is the only thing that distinguishes a baffle from a smooth trim, so on a quote or a submittal it is worth spelling out the trim in words alongside the number.
