Keystone KT-LED12T8-48G-8CSJ-DX2 – Frequently Asked Questions

1) How do I set the color temperature on a Keystone color select T8 tube?
Five settings are built into the lamp: 3000K, 3500K, 4000K, 5000K and 6500K. You pick one per lamp rather than ordering separate SKUs by Kelvin, which is why a single model number covers the whole range. For a property manager standardizing a building, that means one part on the shelf covers the warm 3000K in lobbies and corridors and the 5000K in back-of-house and shops. CRI is greater than 80 at any of the settings.
2) Can I dim these Keystone 48 inch LED T8 tubes?
Dimming on this 12W color-select T8 is accessory dependent, so the lamp alone won't dim on a standard wall dimmer. There's no wireless or app-based control built in either. If the space needs dimming, plan the control gear as part of the design rather than assuming lamp-level dimming.
3) Does the Keystone 12W color select T8 qualify for a utility rebate?
It's DLC listed, which is the qualification most utility prescriptive rebate programs run against for linear LED lamps. It is not on the DLC Premium list, so any rebate tier that requires Premium won't apply. It is not Energy Star rated.
4) How long will these 4 foot LED tubes last before I'm back up the ladder?
Rated life on the Keystone 12W T8 is 50,000 hours. On a 12-hour-a-day office or retail schedule that's over eleven years of service; on 24/7 corridor or parking-structure duty it's closer to five and a half. That is the number to build a relamping cycle around if you're maintaining a portfolio of buildings.
5) Is the Keystone 48 inch LED T8 glass or plastic, and will it show socket shadows?
Frosted glass. The frosting diffuses the diodes so you get an even lit appearance rather than visible dot pattern, which matters in open strip fixtures and wraps where the lamp is in view. Weight is 0.68 lbs per tube, so a full carton is light to carry up a lift, though glass means handling care on a rough job site.
6) Will one 12W LED T8 cover a high bay or warehouse aisle, or do I need more output?
At 1800 lumens each, the Keystone 12W T8 is sized for the fluorescent troffers, wraps and strips it replaces, typically 2 or 4 lamps per fixture in offices, classrooms and retail. For a warehouse aisle at high mounting height you'd be counting on the existing fixture count and reflector to do the work; if the original fixtures were 4-lamp F32T8 strips, a one-for-one swap holds the light level since F32T8 is the stated legacy equivalent. Going to fewer lamps per fixture than the original means recalculating the layout.
