Paper Abstract

The characteristics of medium arc metal halide light sources are defined and discussed. The medium arc is A.C. operated with about 100 watts/mm dissipated in the arc giving arc luminances generally around 12,000 cd/cm2 but, with design compromise, three times this being achievable. The use of metal halides results in very high conversion efficiency into radiation, up to forty percent in some cases, and can provide tailored spectra throughout the near UV and visible wavelengths. The arc's double-ended construction, unjacketed design provides a mechanically precise component suitable for system use.
