Metal vapour lamps
Metal halide lamps feature excellent luminous efficacy while simultaneously having good colour rendition; their nominal service life is high. They represent a compact light source. The light can be optically well directed. The colour rendition is not constant. Metal halide lamps are available in the light colours warm white, neutral white and daylight white and are not dimmed. Metal halide lamps require both starters and chokes for their operation. They require an ignition time of several minutes and a longer cooling-down phase before re-igniting. On some forms an immediate re-ignition is possible using special starters or the electronic control gear.
Metal halide lamps are comparable with high-pressure mercury vapour lamps in design and function. They additionally contain a mixture of metal halides. In addition to increasing the luminous efficacy, improved colour rendition is also attained. Due to combinations of metals, an almost continuous multiline spectrum is produced. Metal halide lamps are available in the light colours warm white, neutral white and daylight white. Compared to quartz technology, the lamps with ceramic discharge tube feature higher luminous efficacy and better colour rendition due to the increased operating temperature.
Metal halide lamps with single-ended cap (HIT) , double-ended cap (HIT-DE) and metal halide reflector lamp (HIPAR)
Metal halide lamps are available as single-ended or doubled-ended tubular lamps, as elliptical lamps and as reflector lamps. Metal halide reflector lamps combine the technology of the metal halide lamps with that of the PAR lamps.
