Topaz Lighting L4T8E/U6/850/13F-70 – Frequently Asked Questions

1) Can I drop this Topaz LED U-bend lamp into my existing fluorescent fixture without rewiring?
Yes, if the fixture runs an Instant Start ballast. The Topaz L4T8E/U6/850/13F-70 is a ballast-compatible (plug-and-play) U-tube that stays on the existing ballast, so you pull the fluorescent U-lamp and put this one in. No rewiring, no ballast bypass, no relamping the sockets. If the fixture has a programmed start or rapid start ballast, or the ballast is failing, this is not the lamp for that job.
2) Does this Topaz U-tube work on 277 volt commercial panels?
Yes. The lamp operates across 120-277VAC, so it covers both 120V single-phase branch circuits and 277V lighting circuits common in offices, schools and warehouses. One part number works across both, which keeps a mixed-voltage building on a single stocked item.
3) What should I check in the fixture before ordering Topaz U-bend LED lamps for a whole building?
Three things. First, the ballast type: these run on Instant Start ballasts only. Second, the existing lamp geometry, since U-bend fluorescents come in different leg spacings and the replacement has to match the socket centers in your troffer. Third, the color temperature already in the building, because this lamp is 5000K and mixing it with warmer tubes in the same room shows. Get those right and the swap is lamp-for-lamp on the existing 120-277V circuit.
4) Is the Topaz 13W LED U-tube single-ended or double-ended?
Single-ended. The 13W U-bend takes its power through one end, which matters because the lamp rides on the existing Instant Start ballast rather than on line voltage through both sockets. Nothing changes at the fixture sockets during a swap.
5) What color light does the Topaz 5000K U-tube put out, and will it match my other tubes?
5000K, a crisp daylight white. If the rest of the building is on 3500K or 4000K lamps, this will read noticeably bluer next to them, so for a partial retrofit in the same room or sightline, stay on one color temperature across the space.
6) How long does the Topaz LED T8 U-tube last before it needs changing?
Rated at 50,000 hours, roughly twice the rated life of comparable fluorescent U-lamps. For a facility burning 12 hours a day that is a long relamp interval, which is usually the whole argument for the retrofit when the ladder time and lift rental cost more than the lamps.
7) Why choose a frosted U-tube instead of a clear one?
The frosted diffuser knocks down glare and smooths the output, which is what you want in offices, classrooms and any space where people work under the fixture with no lens or only an open louver. A clear lens pushes more punch but shows the diodes. This Topaz lamp is the frosted version.
8) What is the manufacturer part number for the Topaz 13W 5000K frosted LED U-tube?
Topaz Lighting L4T8E/U6/850/13F-70. That single part covers the 13W, 5000K, frosted, single-ended ballast-compatible U-bend lamp, so it is the number to quote for a reorder or a standardization list.
