Product Details

GE ConstantColour™ CMH-TD Double Ended Ceramic Metal Halide Lamps

ConstantColor™ CMH lamps combine the HPS (High Pressure Sodium) 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. 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.

Suitable applications for this lamp include:
City beautification
Architectural lighting
Display Cabinets

Consistent colour over life
Colour uniformity lamp to lamp
Bright light – in a very compact size
Excellent colour rendition
Improved reliability due to 3 part design
Up to 97 LPW efficacy
15,000 Hr life
UV control
Easy retrofit for Quartz Metal Halide lamps
3000K and 4200K colour temperature

Ceramic Metal Halide

These lamps are fully compatible with the traditional metal halide type, with the same physical dimensions, also using use the same control gear
The clear outer Quartz envelope is UV- block
Constant colour temperature maintained without the colour drift experienced by the traditional type
Improved colour rendering and light (lumen) output


These lamps require 2 to 10 minutes to cool before re-striking, but shorter times are possible if installed in fittings with high voltage ignitor circuits.
