The Auroralight Power Canopy mount is designed for surface mounting the Sumatra Series Ceramic metal Halide directional luminaires to standard building mounted flush, 3" or 4" round J-boxes where 120 volt service is present. Machined from solid brass for extreme durability, these fixture mounts are built to the same quality specifications as our entire family of fixtures. Our proprietary screwless faceplate eliminates twisted wires and visible screws to make installation fast and neat. Specify 20 or 39 watt configuration to meet your design needs. This power canopy features a GE Ultramax electronic HID ballast for superior lumen maintenance and long life with low maintenance.
