The TWX LED wall pack family features a ground-up design with a low initial cost customers demand while providing superior performance in a traditional form. The TWX LED wall packs feature premium borosilicate glass lenses that work in conjunction with the high-efficiency light engine to provide superior illumination while minimizing wasted up-light. The new slim design creates a less obtrusive appearance on the building while still fully covering the unsightly stains leftover from typical HID glass wall packs. The Adjustable Light Output (ALO) option maximizes flexibility both in the field and on distributor shelves.
