ComboDrive X3 T8 LED tubes offer maximum flexibility in both technology and application. With single- or double-ended wiring constructions and selectable CCT, and the ability to use them as either a UL Type A LED tube with an instant start ballast or a UL Type B LED tube in a ballast bypass application, it’s the ultimate lamp.
The selectable CCT version allows users to choose from among five color temperatures – 3000K, 3500K, 4000K, 5000K, and 6500K – making this versatile tube an ideal replacement for conventional fluorescent lamp, single- or double-ended line voltage wiring.
Installation is simple. For the plug-and-play application, the tube can be installed without any changes to the fluorescent ballast wiring – just switch out the fluorescent tubes with T8 LED tubes. Should the instant start ballast fail, simply take it out and connect the T8 LED tube directly to the line voltage. This allows you to keep using the same lamp instead of replacing it.
For the ballast bypass option, just connect the tube directly to the 120-277V line voltage following the wiring diagrams. They’re compatible with most instant start electronic T8 ballasts. Keystone offers replacement lamp holders if needed.
ComboDrive X3 T8 tubes are approximately 60% more energy-efficient than standard F32T8 lamps, feature a 50,000+ hour lifetime, and are dimmable with compatible dimming ballasts.
