Always follow the supplied lamp operation and handling instructions.

Lamp technology

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. This is achieved by using the ceramic arc tube material from the Lucalox™ lamp, which minimises the chemical changes inside the lamp through life. When combined with the halide doses used in Arcstream™ Metal Halide lamps then the quality and stability of the dose maintains the colour consistency. Hence the name ConstantColor CMH™.

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.

Single ended format

Single ended Ceramic Metal Halide lamps are designed to provide symmetrical beam distribution using the axial con- figuration of the discharge arc.

A variety of beam angles are possible and adjustable beam control can be built into the luminaire.

This compact lamp shape enables luminaire size to be minimised and the bi-pin lamp base enables easy changing with front access.
