Lithonia Lighting® TWX LED wall pack family’s ground-up design delivers superior illumination in a traditional form while providing the low initial cost that customers demand. 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 metal halide glass wall packs. The TWX1 LED is energy efficient saving up to 83% in energy costs when replacing a metal halide luminaire. The Adjustable Light Output (ALO) feature allows the contractor to set the light output during installation, to a level perfectly suited for the job site. The TWX1 LED ALO luminaires can replace anything from a CFL to 100W metal halide luminaire.
