  • The best of both worlds! Combine the ease of initial installation and the energy independence of both a ballast-compatible and ballast-bypass LED tube all combined into one convenient product. Instantly convert your existing T8 electronic ballasted fluorescent fixtures to LED by directly changing out the tubes, and when you’re ready to do away with the fluorescent ballasts (or if you have a T12), simply bypass the ballast wiring and run the input lines straight into the LED Hybrid tube for even more energy savings!

    * DLC Qualified: When installed as a direct plug-in bulb.

    Not compatible with T12 Magnetic ballasts. T8 instant start electronic ballast required to use ballast compatible mode. When using in ballast bypass mode: T8 fixtures require non-shunted lamp holders (tombstones). Not for use with dimmers.
