Keystone KT-LED14.5T8-48G-840-DX2 – Frequently Asked Questions

1) Can I install this Keystone 14.5W LED T8 tube in my existing fluorescent fixture without rewiring?
No. The Keystone KT-LED14.5T8-48G-840-DX2 is a direct drive (ballast bypass) tube, so the fixture's fluorescent ballast has to be removed or bypassed and line voltage wired to the sockets before the tube goes in. It will not run off an existing fluorescent ballast. If you want a drop-in that runs on the ballast you already have, you need a plug-and-play (Type A) tube instead.
2) Will a 14.5W LED T8 tube be bright enough to replace a 32W F32T8 fluorescent lamp?
For general office, retail, and corridor lighting, yes. The Keystone 4-foot LED T8 draws 14.5W and puts out 1900 lumens with a 240 degree beam spread, so a typical multi-lamp troffer retrofit lands in the same usable range as the F32T8 lamps it replaces while cutting draw by more than half. For high-bay or task areas where you were already short on light, step up to a higher lumen tube rather than this one.
3) Does this Keystone LED T8 work on 277V commercial circuits as well as 120V?
It runs anywhere from 120 to 277 volts, so the same tube covers 120V tenant spaces and 277V building circuits. For a property manager or MRO buyer standardizing across a facility, that means one part number stocked instead of separate voltage SKUs.
4) Is this LED tube DLC listed so I can claim a utility rebate?
The Keystone 14.5W LED T8 is DLC 4.0 qualified, which is what most utility prescriptive rebate programs and green building programs ask for on linear LED retrofits. Confirm the current qualified products list entry with your utility before you submit the application, since program requirements change.
5) Is a direct drive LED tube a good choice for a large retrofit, or should I use plug-and-play?
Direct drive makes sense when you are relamping a whole building and want the ballast out of the system for good: one rewire at the fixture, then no ballast to replace over the 50,000 hour life of the tube, and the tube runs on anything from 120 to 277 volts. Plug-and-play is the faster option for scattered one-off replacements where you do not want an electrician at every fixture. The trade-off is labor now versus maintenance later.
6) How long will these LED T8 tubes last before we have to relamp again?
Rated life is 50,000 hours. On a 12-hour-a-day, 5-day schedule that is roughly 16 years of operation, which is why the direct drive design matters on a fleet of fixtures: with the ballast out of the circuit there is no ballast to fail in the interim either.
