   A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI). [3] Applications for these lamps include shop lighting, street lighting ...

   A metal halide bulb produces 60-125 lumens/watt, depending on the wattage of the bulb. [24] They are now being made for digital ballasts in a pulse start version, which have higher electrical efficiency (up to 110 lumens per watt) and faster warmup. [25] One common example of a pulse start metal halide is the ceramic metal halide (CMH).

   However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Metal-halide and ceramic metal-halide lamps can be made to give off neutral white light useful for applications where normal color appearance is critical, such as TV and movie production, indoor or nighttime sports games, automotive ...
