CDM Outdoor ParThe Outdoor-Par-CDM luminaire, constructed of cast aluminum, utilizes non-corroding hardware and fittings. All joinings have heavy gaskets to protect the lamp, the reflector and internal integral ballast, from the ravages of inclement weather. Both the 70 watt and 150 watt units incorporate a reflector designed to operate efficiently with the Ceramic Discharge Metal Halide lamps, and both units are U.L. and C.U.L. listed with their respective lamps.
