Keystone Technologies LED Lighting Tubes and Wiring Harnesses


With the exponential rise in utility costs and the use of electrical and electronic equipment, it is now more important than ever to have your lighting systems functioning at their optimum. Upgrading lights to LED is one of the easiest and most cost-effective ways to impact your company's bottom line.

SMC’s innovative DirectDrive LED tubes eliminate the need for an external driver or ballast. By using a ballast bypass design, there’s one less possible point of failure, making the fixture more reliable. Ballast bypass LED tubes will also save time in finding a compatible ballast.

Upgrading fluorescent lights to LED will save time and money in maintenance costs. When a fluorescent light is frequently turned on and off the lifespan is reduced, whereas LED tubes aren’t affected nearly as much. Upgrading fluorescent lights to LED will also improve the quality and energy efficiency of a lighting system. UL Type B LED tubes prevent energy from being wasted as it passes through a ballast.

DirectDrive LED tubes is perfect for new construction or retrofit installations, simply connect the 120-277v line voltage directly to the sockets. For retrofit installations, bypass the existing ballast by cutting the wires and connecting the 120-277v line voltage directly to the sockets. No ballast or driver is required.

Take the guesswork out of ballast compatibility with DirectDrive LED tubes.
