HMI-type light fixtures are designed by lighting technicians for lighting technicians as high-efficiency daylight booster discharge lights that approximate the color of sunlight.  HMI-type fixtures are built with corrosion resistant extruded and die cast aluminum to maximize body strength and create a lighter fixture weight for ease of use.

*HMI is an Osram brand metal-halide gas discharge lamp and the HMI designation has become a generalized term in the motion picture and television industries for all similar metal-halide lamps.
