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 TWX3 LED is energy efficient saving up to 84% 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 TWX3 LED ALO luminaires can replace anything from a 100W to 400W metal halide luminaire.
