The most economical, practical and user friendly series of LED fixtures with the energy savings, quality of light, long life and hassle-free maintenance. X1 LED fixtures are UL Listed with the latest LED T8 Bypass lamps. Fixtures provide over 44% energy savings over comparable fluorescent fixtures utilizing less expensive fixtures than the fluorescent version (no ballast required) and have flexibility to change wattage and color temperature any time. Fixture performance will evolve over time with the evolution of the T8 LED lamp technology. Concerned about maintenance with an LED array and driver fixture, X1 LED solves that by utilizing a self contained LED lamp that fits into fixture just like a fluorescent lamp. Designed to convert 4’ or 8’ T8 industrial and strip fixtures to more efficient T8, T5 or LED technology. Choose between retrofitting with a reflector for enhanced performance or simply a ballast cover. Both kits utilize a Universal Socket Bracket engineered to fit most fluorescent channels from 4” to 5.25” in width. The Reflector/Ballast Cover mounts to socket brackets with quarter-turn fasteners for easy maintenance after retrofit is complete. The Universal Socket Bracket ships flat and easily folds to fit channels and requires only simple hand tools. The X1LED SKR series utilize efficient LED T8 lamps that provide high lumen output with efficient energy savings. Since they don’t require any ballast or driver the only component that will ever need changing is the LED T8 lamp. The lamps are warranted for five years. Unlike SKR series that utilize LED arrays and drivers these fixtures have the flexibility to change wattage, lumens, and color temperature simply by changing the lamps without the need to call a licensed electrician.

1, 2 or 3 lamp positions

The SKR universal strip retrofit kit mounts easily, requiring only simple hand tools. The process includes removal of the existing ballast cover(s) and removal of the existing socket brackets and ballast. The new reflector is then attached to the existing strip channel with a universal socket bracket and self-tapping screws. The universal socket bracket can fit channels from 4” to 5 1/4” in width. The reflector serves as the ballast cover. Mount and connect new ballast to sockets. Close the reflector using captive quarter turns and install lamps.
