Abstract: In the modern stage, studio, TV, film, and special effects marketplace, there is an increasing demand for compact light sources that provide high luminous efficiency, daylight color temperature, and good color rendering. An additional requirement for these light sources is that they be capable of convenient mounting and of optical compatibility with existing fixture designs. OSRAM Corp., the first manufacturer to develop medium arc metal-halide lamps, has met this need by forming a family of single-ended metal-halide lamps: HMI® 123, HMI 250 W/SE, HMI 400 W/SE, HMI 1200 W PAR, HMI 1200 W/SE, and HMI 2500 W/SE. This article addresses the development of the HMI/SE lamp family, lamp designs, specific lamp characteristics, operation with electronic power supplies, dimming capabilities, and practical applications.
