This Replacement Light Head is for use with the Portable Incandescent Utility Lights. It is ideal for any garage or workshop environment. Incandescent work lights use standard R-40 or PAR incandescent bulbs up to 300 watt flood lights. (Bulbs not included.) Metal halide lights are yoke-mounted to allow easy vertical and horizontal angle adjustments. Lights are housed in yellow powder-coated steel for strength and safety. Incandescent lights offer an average life of 2,000 hours.
