Features a light-weight, rust proof aluminum body. Major brand solid state electronic ballasts (no copper windings) do not emit heat, noise or vibration. Smart Volt" ballasts can run on 120, 208, 240 & 277 volt input power. Unique design places ballasts outside lamps (instead of above lamps as in competitive fixtures) for longer fixture life.
