RAB T8-14-48G-840-HYB – Frequently Asked Questions

1) Can I install this RAB T8 LED tube without removing the existing fluorescent ballast?
Yes. The RAB T8 glass LED tube is a hybrid Type A+B lamp, so it will run off an existing compatible fluorescent ballast as a plug-and-play swap, or you can bypass the ballast and direct wire it. That flexibility is the main reason to pick a hybrid: you can drop tubes in now and convert the fixture to direct wire later when the ballast fails, without buying a different lamp.
2) Will this 4-foot LED tube fit a standard 4ft fluorescent troffer or strip fixture?
The tube measures 47.24 inches long and 1.18 inches in both height and width, which is the standard nominal 4-foot T8 envelope, so it seats in 4ft troffers, wraps and strip fixtures built for F32T8 lamps. Sockets are the usual bi-pin tombstones on that fixture type.
3) Which wattage and color temperature combinations can I order in the RAB glass hybrid T8?
Four combinations: 12W or 14W, each in 80 CRI 4000K or 80 CRI 5000K. Part numbers are T8-12-48G-840-HYB, T8-12-48G-850-HYB, T8-14-48G-840-HYB and T8-14-48G-850-HYB. 4000K reads neutral white for offices and classrooms; 5000K is the crisper daylight tone usually specified for warehouses, shops and healthcare corridors. Keep one color temp across a room or the mismatch will be obvious.
4) What voltage does the RAB hybrid T8 tube run on when it is direct wired?
In Type B (direct wire) mode the tube accepts 120-277V, which covers the usual 120V and 277V commercial branch circuits. In Type A mode the input is ballast dependent, so the existing ballast determines the supply.
5) How much light does this tube put out compared to the 32W fluorescent it replaces?
Output is 1800 to 2150 lumens at 12W or 14W. That is well under the wattage of a standard 32W T8 fluorescent, so the savings per lamp is substantial, but the lumen package is lower than a high-output 32W lamp. For general office, retail and corridor lighting on a one-for-one swap it works; for a space where the existing fixtures are already marginal, count the fixtures before assuming the retrofit holds the footcandle level.
6) If I direct wire these tubes, does anything else in the fixture need to change?
Going Type B means the fluorescent ballast comes out and line voltage lands on the sockets, so the fixture has to be relabeled as converted and the tombstones need to suit the wiring scheme. Nothing in the lamp itself changes, the same hybrid tube runs either way on 120-277V. If you would rather not open fixtures, leave the ballast in place and run them Type A.
7) Glass or plastic T8 LED tube, which should I use?
This RAB tube is glass bodied with a white finish. Glass holds its shape and appearance well in office, retail and healthcare spaces and keeps the familiar fluorescent look. Where tubes are exposed to impact, in gyms, shops or low warehouse aisles, a shatter-resistant coated or polycarbonate tube is the better call.
