Color Selectable LED Linear Tube Lights FAQs
What is a color selectable LED linear tube light?
A color selectable LED linear tube light is a T5, T8, or T12 LED tube that lets you switch between multiple white color temperatures — typically 3000K soft white, 4000K cool white, and 5000K daylight — using a built-in selector switch. Feit Electric color selectable LED linear tubes are direct replacements for fluorescent tubes and require no app, no Wi-Fi, and no smart home hub. They work in offices, garages, warehouses, schools, and utility spaces.
What is the difference between T5, T8, and T12 LED tubes?
T numbers indicate tube diameter in eighths of an inch. T5 (5/8 inch diameter) is the slimmest — used in under-cabinet fixtures, display cases, and compact fluorescent housings. T8 (1 inch diameter) is the most common — used in office, retail, and commercial fluorescent fixtures. T12 (1.5 inch diameter) is the oldest standard — found in older commercial and industrial fixtures. Always match the LED tube type to your existing fixture size before purchasing.
What is the difference between direct wire and ballast compatible LED tubes?
Ballast compatible (plug-and-play) LED tubes work with your existing fluorescent ballast — no rewiring required, straightforward swap. Direct wire (ballast bypass) LED tubes require removing or bypassing the ballast and connecting the tube directly to line voltage — more installation work upfront but eliminates ballast failure as a future maintenance issue. Feit Electric color selectable LED linear tubes are available in both configurations. Check the product specifications to confirm compatibility with your fixture.
How do you change the color temperature on a Feit Electric color selectable LED tube?
Feit Electric color selectable LED linear tubes include a built-in CCT selector switch on the tube or fixture end cap. Slide or toggle the switch to choose between 3000K, 4000K, and 5000K before installation while the tube is off. The selected color temperature holds until you manually change it — no app, no power cycling, no hub required.
Can Feit Electric color selectable LED tubes replace fluorescent tubes?
Yes. Feit Electric color selectable T5, T8, and T12 LED linear tubes are direct replacements for standard fluorescent tubes. They use up to 50% less energy than fluorescent, produce no flicker, contain no mercury, and last up to 50,000 hours. Available in ballast compatible and direct wire configurations to fit most existing fluorescent fixtures without replacing the housing.
