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.

The HBG Series open frame fluorescent high bay is a fully accessorized open frame fixture for warehouse lighting. Premium full specular mirrored reflectors provide efficient lighting and maximum throw for medium to high mount applications. Built tough for industrial applications. Fully accessorized, the X1LED HBG 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 chaning is the LED T8 lamp. The lamps are warranted for five years. Unlike HBG 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.
