RAB T8-14-48G-835-DE-BYP – Frequently Asked Questions

1) Do I have to remove the ballast to install the RAB T8 14W LED tube?
Yes. The RAB T8-14-48G is a double-ended ballast bypass lamp, so the existing fluorescent ballast has to come out and line voltage is wired to one end of the socket pair and neutral to the other. Double-ended means power comes in at one end and neutral at the other, not both pins on a single end. It accepts 120-277V, so it drops onto standard commercial branch circuits without changing lamp part numbers between a 120V and a 277V building.
2) What color temperatures does the RAB 4-foot 14W T8 LED tube come in?
Four: 3000K, 3500K, 4000K and 5000K, ordered as T8-14-48G-830-DE-BYP, -835-DE-BYP, -840-DE-BYP and -850-DE-BYP. If you are relamping a building in stages, pick one number and stick with it - mixing 3500K and 5000K in the same space is visible from across the room. 5000K reads as crisp daylight and is the usual choice for warehouses and shops; 3500K blends better with older fluorescent offices.
3) Is the RAB T8 LED tube glass or plastic, and does that matter for a healthcare or food area?
It is a glass tube with a white finish. Glass holds its appearance and does not yellow the way some polycarbonate housings can, but it breaks. In kitchens, food processing, gyms or anywhere a shatter-resistant or coated lamp is specified, a glass tube is the wrong call and you want a plastic-bodied or coated T8 instead.
4) Does the RAB 14W T8 LED tube qualify for utility rebates?
It is listed to DLC version 5.1, which is the qualification most utility prescriptive rebate programs check against for linear LED replacement lamps. Rated life is 50,000 hours. Utilities publish their own current DLC version requirement and lamp category, so confirm which list your program is paying from when you file.
5) Can I use one lamp type across a building that mixes 120V and 277V panels?
Yes. The RAB T8-14-48G runs on 120-277V, so the same lamp goes into a 120V back-of-house strip and a 277V office troffer. That is the practical argument for standardizing on it across a portfolio - one part number in the stockroom instead of voltage-specific stock.
6) How much does the RAB 4-foot T8 LED tube weigh?
0.56 lb per lamp. Light enough that it adds no meaningful load to an existing lay-in troffer or suspended strip, so you are not re-evaluating hanger or grid capacity when you relamp a floor.
