Ceramic discharge metal halide lamp
From Wikipedia, the free encyclopedia
Ceramic discharge metal halide lamps are a relatively new source of light that is a variation of the mercury-vapor lamp. There is a ceramic tube inside the lamp that heats a mercury-argon mixture creating a blueish light that is close to daylight with a CRI (color rendering index) of 96. They are five times brighter than comparable tungsten incandescent light bulbs.
Applications for these lamps include television and film making as well as digital photography and architectural lighting.
