RAB Lighting has released the 37-watt SLIM37, 57-watt SLIM57 and 62-watt SLIM62 LED wallpacks to replace metal halide fixtures ranging from 150 to 320 watts. The wallpacks, which can reduce energy and maintenance costs by up to 70 percent, offer a design that fits most traditional wallpacks’ footprints to cover stains and blemishes discovered when replacing wall fixtures. The SLIM fixtures are suitable for mounting heights from 20 to 30 feet and are available in standard, cut-off and full-cut off versions.
