Ceramic Metal Halide - Tubular Clear

ConstantColor CMH Tubular Clear

ConstantColor™ CMH lamps combine HPS technology (providing stability, efficiency & uniformity) and Metal Halide technology (providing bright white quality light) to produce highly efficient light sources with good colour rendering and consistent colour performance through life.

Metal halide lamps, traditionally made with quartz arc tubes, are prone to colour shift through life and lamp-to-lamp colour variation. Some of the dose, e.g. sodium, (an important component of metal halide lamps), can migrate through quartz to cause colour shift and loss of light through life. The ceramic arc tube resists this material loss, can be manufactured to tighter tolerances and withstands a higher temperature to provide a more constant colour.


Product information

ConstantColor™ CMH lamps combine the HPS technology (providing stability, efficiency & uniformity) and the Metal Halide Technology (providing bright white quality light) to produce highly efficient light sources with good colour rendering and consistent colour performance through life.

Conventional lamp shape with a screw-type base enables existing luminaire designs to use ConstantColor™ CMH lamps with little or no modification to the optical system
