Product Details

HID lamps are compact, with high light output and life ratings better than incandescents and similar to fluorescents. Like incandescents, HID lamps provide a point light source that allows good optical control. Metal halide lamps deliver sparkling white light, effective for stores, displays, and accent lighting.
