Keystone Technologies makes commercial LED lighting and power components, and this category lists nearly 1,300 Keystone products. They include LED T8 and T5 tubes, LED PAR lamps, metal halide lamps, LED drivers, electronic fluorescent ballasts, retrofit kits, LED panels and troffers, high bays, area lights, wall packs and LED emergency backup kits.
How do I pick the right Keystone LED tube or lamp? Check how it is wired. Ballast-compatible (Type A) and direct-wire bypass (Type B) products install differently. Then match the base and the wattage or lumens you are replacing. Many fixtures have selectable color temperature, and many listings note DLC qualification for utility rebates. Facility and contractor buyers can call 1-800-492-9660 about project quantities. Orders of $500 or more ship free within the contiguous US.
