RAB T8-12-48G-8CCT-HYB – Frequently Asked Questions

1) Will the RAB T8 LED tube work in my existing fluorescent fixtures without rewiring?
Yes, and that's the point of the Type A+B hybrid design. The RAB T8 4-foot LED tube runs off an existing fluorescent ballast (Type A) so you can drop it into a working fixture with no electrical work, or you can bypass and remove the ballast and direct-wire it (Type B). Type B operation runs 120-277V, so it covers both the 120V and 277V circuits you'll find across a commercial building. On Type A the input is ballast dependent, meaning the lamp only performs as well as the ballast it's sitting on. The common approach on a large retrofit is to relamp on the ballast now, then convert to direct wire as ballasts fail, which is exactly what the hybrid lamp lets you do without buying a second SKU.
2) What is the difference between the 12W and 15W RAB T8 LED tube?
Output. Both are 4-foot glass T8 lamps with the same hybrid Type A+B wiring and the same 5CCT selectable color, and the pair covers 1650 to 2100 lumens across the range. The 12W (T8-12-48G-8CCT-HYB) is the lower-output, lower-draw option and suits offices, corridors, and retail where you are relamping 32W fluorescent with plenty of fixture density. The 15W (T8-15-48G-8CCT-HYB) gives you the higher end of the lumen range for warehouse aisles, shops, and storage areas where fixtures are spaced further apart or mounted high. If you are matching an existing lit level rather than cutting it, count the fixtures per square foot before you pick.
3) Will a 4-foot RAB T8 LED tube fit my existing 48 inch fluorescent troffer?
It fits a standard 4-foot T8 fixture. The lamp measures 47.8 inches long and 1.08 inches in both height and width, which is the nominal 4-foot T8 lamp envelope, so it seats in the same lampholders as the F32T8 you are pulling out. The 1.08 inch diameter is what T8 means (eight eighths of an inch), so it will not fill the socket gap in a T12 fixture the way a T12 lamp did, though the pins are the same medium bipin. At 0.44 lb each, a case of these is far lighter to carry up a lift than the glass fluorescents coming down.
4) Does the RAB T8 LED tube qualify for a utility rebate?
It's listed on the DesignLights Consortium QPL to DLC version 5.1, which is the qualification most commercial utility programs point at for linear replacement lamps. That listing is what a rebate administrator checks, so for a property manager or facility buyer running a lighting retrofit through a utility incentive, this lamp is on the right side of that requirement. File the model number with your rebate paperwork.
5) Should I buy a Type A, Type B, or hybrid LED tube for a retrofit?
Depends on how much labor you want to spend and what shape the fixtures are in. Type A only is the fastest install, lamp swap and walk away, but you inherit every ballast in the building and its eventual failure. Type B only is direct wire, which means an electrician at every fixture to bypass the ballast, but the ballast is then gone for good and you own the whole light path. The RAB T8 hybrid is both, so you don't commit at purchase order time. Relamp on the existing ballast today, and when a ballast fails, bypass that fixture and reinstall the same lamp instead of buying a different one. For a large portfolio where fixture condition varies floor to floor, that is the reason to pay for hybrid over a single-type lamp.
6) How do I change the color temperature on a 5CCT selectable LED tube?
Selection is made at the lamp, in the field, before or at install. The RAB T8 hybrid carries five selectable color temperatures on a single lamp, which is why one SKU covers an entire building. Practically it means a contractor stocks one tube on the truck instead of separate 3500K, 4000K, and 5000K lamps, and a property manager can match the corridor to the offices later without reordering. Set every lamp in a room to the same setting; mixed settings in one space read as a color mismatch even when both are correct.
7) Are these LED tubes low flicker enough for offices and classrooms?
Flicker is rated under 40 percent, driven by a constant current driver rather than a cheap AC-direct arrangement. That matters most in the spaces this lamp is aimed at, offices, schools, and healthcare, where people sit under the light all day and where flicker complaints and headache reports come back to the facilities desk. Worth noting: on Type A operation the lamp is running through your existing ballast, so an old or failing ballast can affect what you actually see. Direct wire gives you the cleaner result.
8) How long do RAB T8 LED tubes last compared to fluorescent?
Rated life is 50,000 hours. On a 12-hour-a-day, 5-day commercial schedule that's roughly 16 years of service, which is the whole argument for relamping an MRO or multi-family portfolio in one pass: you take the ladder out of the maintenance budget rather than shaving a few watts. Compare that against the 20,000 to 30,000 hours typical of the F32T8 fluorescent being removed, plus the ballast failures that come with it.
9) Can I use one LED tube on a 277V circuit and another on 120V in the same building?
Yes, when they're direct wired. Type B operation on the RAB T8 accepts 120-277V, so the same lamp works on the 120V branch feeding the front office and the 277V circuit feeding the warehouse bays. That's the case for standardizing a mixed-voltage facility on a single part number rather than stocking a 120V lamp and a 277V lamp. On Type A the lamp is running on whatever the existing ballast provides, so voltage is settled by the ballast already in the fixture.
10) Is the RAB T8 hybrid tube glass or plastic?
Glass. Both the 12W and 15W versions are built on a glass tube with a white finish. Glass gives you the cleaner optical surface and better heat handling; where a facility needs a shatter-resistant or coated lamp, food processing areas and some healthcare and school specifications, glass is what your specifier will be looking at, so confirm the requirement before you standardize a whole building on it.
