- The CLCS canopy Luminaire provides a slim, low-profile, traditional design with high performance energy efficient illumination. Rugged die-cast aluminum construction and gasketed housing make the CLCS Luminaire virtually impenetrable to contaminants. Replacing up to 400 W metal halide equivalents, the CLCS canopy Luminaire mounts quickly to a variety of surfaces making it ideal for bank and retail drive-thrus, covered side walks and hospitality entryways.
