This 42 watt compact fluorescent wall pack provides years of energy savings and maintenance-free operation. The die-cast aluminum fixture has a shatter resistant, polycarbonate lens. Though it replaces a metal halide fixture of more than twice the wattage, it offers greater lumens per watt and lower maintenance costs. For ease of installation, it can be used in 120 or 277 volt settings. 42W CFL is included.
