RAB T5HO-18-36G-850-DIR – Frequently Asked Questions

1) Can I leave the existing T5HO ballast in place when installing the RAB LED tube, or do I have to rewire the fixture?
The RAB T5HO LED tube is a ballast-compatible (Type A) lamp, so it runs off the existing T5HO ballast with no rewiring. Drop it into the same G5 sockets and you are done. The catch is that not every ballast is on RAB's approved list, so match the ballast model against RAB's T5HO glass ballast compatibility document before committing to a building-wide relamp. If the ballast is failing or unlisted, you are back to a ballast-bypass product instead.
2) Which length and wattage RAB T5HO LED tube replaces a 54W 4 ft fluorescent T5HO lamp?
The 4 ft version draws 25W and comes as T5HO-25-48G-840-DIR in 4000K or T5HO-25-48G-850-DIR in 5000K. The family also covers 3 ft at 18W and 2 ft at 9W, so you order by the physical length of the lamp already in the fixture, not by the old wattage.
3) Should I buy a ballast-compatible LED tube like this RAB or go with a ballast-bypass retrofit?
Ballast-compatible is the right call when the existing T5HO ballasts are healthy and you want the fastest possible relamp with no electrician touching the fixture wiring. The RAB T5HO tube runs on a constant current driver off the existing ballast, so a maintenance tech can do the swap. Go ballast-bypass instead when the ballasts are already failing, when you want to eliminate the ballast as a future maintenance item, or when the installed ballasts are not on RAB's compatibility list. Bypass means rewiring the sockets, which is licensed electrician work.
4) Will these RAB LED tubes work on 277 volt commercial circuits as well as 120V?
Yes. Operating range is 120-277V, so the same tube covers 120V tenant spaces and 277V commercial or industrial panels. That matters when you are standardizing one part number across a portfolio with mixed voltage.
5) Do the RAB T5HO LED tubes qualify for utility rebates?
They carry a DLC listing at version 5.1, which is the qualification most utility rebate programs check against. Confirm your specific utility's current DLC version requirement and the exact model number on your rebate paperwork.
6) What color temperatures do the RAB T5HO LED tubes come in, and which should I use in an office versus a warehouse?
Two choices across every length: 4000K and 5000K, both at 80 CRI. 4000K is the neutral white typically specified for offices, retail, and healthcare corridors; 5000K reads cooler and is the common pick for warehouses, shops, and parking structures. Keep one temperature per space, since mixing 840 and 850 tubes in the same room is visible.
7) These RAB retrofit tubes are glass, not plastic. Does that rule them out for a school or food area?
The tube body is glass, so in food prep, food processing, or anywhere a shatter-resistant lamp is required by the facility's own policy, you would want a coated or plastic-body lamp instead. For offices, retail, classrooms, back-of-house, and warehouse fixtures with lenses, glass is standard and the glass build is what allows the ballast-compatible electronics in this design.
8) What is the tube diameter on the RAB T5HO LED lamp, and will it clear a tight T5 fixture channel?
Height and width are both 0.79 inches, which is a round tube of that diameter, the same nominal T5 envelope as the fluorescent lamp coming out. It seats in existing T5HO fixture channels and lamp holders without modification. Finish is white.
9) How long do the RAB T5HO LED tubes last compared to the fluorescent lamps I'm pulling out?
Rated life is 50,000 hours. On a 12-hour-a-day commercial schedule that is roughly 11 years of service, which is the case for relamping a whole building at once rather than spot-replacing fluorescents as they fail. Note that the lamp life does not extend the ballast's life, so an aging ballast can still be the thing that takes the fixture down.
