Topaz Lighting L2T5E/840/9/F-70 – Frequently Asked Questions

1) Do I have to rewire my T5 fixture to install the Topaz L2T5E840 LED lamp?
No rewiring. The Topaz L2T5E840 is a ballast-compatible (Type A) LED T5 tube that runs off the existing program rapid start T5/HO ballast already in the fixture. You pull the fluorescent tube, drop the LED in, and you are done. The tradeoff is that the lamp depends on that ballast, so if the ballast fails later you either replace the ballast or move to a ballast-bypass lamp.
2) Will these fit T8 fixtures, or only T5?
T5 only. This is a T5 lamp with T5 miniature bi-pin ends, and it is built to run on program rapid start T5/HO ballasts. T8 fixtures use a larger tube diameter and medium bi-pin sockets, so the lamp will not seat and the ballast will not match. For a T8 troffer you need a T8 replacement lamp instead.
3) Will this Topaz T5 LED lamp work on 277 volt commercial circuits?
Yes. The Topaz L2T5E840 T5 lamp is rated 120-277VAC, so it covers both 120V branch circuits in small commercial spaces and 277V lighting circuits common in office buildings and schools. One part number works across both, which is useful when you are standardizing lamp stock across a mixed-voltage facility.
4) Is 5000K too cool for an office retrofit, or is it the right color for the space?
5000K is a daylight-white light, noticeably crisper and bluer than the 3500K or 4100K fluorescent tubes many older offices were built around. It reads well in open office, retail, classroom and institutional spaces where you want brightness and contrast. If you are relamping only part of a building, expect a visible color mismatch against any 3500K or 4100K tubes left in adjacent fixtures, so plan to do whole rooms or whole floors at a time.
5) Can I use these LED T5 lamps in a food prep area or school where shatter protection is required?
The tube is frosted glass with a PET coating that holds glass fragments together if the lamp breaks. That is the standard construction specified for areas where falling glass is a concern, such as food handling spaces, kitchens, and schools. Confirm your facility's own written policy on lamp safety, since some operations require a specific coated-lamp standard by name.
6) How long do these Topaz LED T5 tubes last compared to the fluorescent tubes I'm pulling out?
Rated functional life is 50,000 hours. On a 12 hour a day, 5 day a week office schedule that is roughly 16 years of service, which is why property managers and MRO buyers use this kind of swap to get lamp changes off the maintenance schedule entirely. Topaz also states up to 40 percent energy savings against comparable fluorescent sources.
7) Can I install these in an enclosed troffer or a suspended strip fixture?
Both are listed applications for the Topaz T5 LED lamp, including suspended troffer and strip fixture installations as well as general office retrofits and renovation work. Because the lamp reuses the existing program rapid start ballast, the fixture itself stays as-is, which keeps ceiling work down to opening the lens and swapping tubes.
