    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. This is achieved by using the ceramic arc tube material from the LucaloxTM lamp, which minimises the chemical changes inside the lamp through life.

Features

  • Easy retrofit for High Pressure Sodium lamps
  • No ballast thermal protection required
  • Consistent colour over life
  • Colour uniformity lamp to lamp
  • Excellent colour rendition (CRI: 80+)
  • Up to 24% higher efficacy than Quartz Metal Halide
  • Up to 20,000 hours life
  • UV control

Dimming

In certain cases, dimming may be acceptable, subject to further testing. Contact your GE representative for more information. Large changes in lamp power alter the thermal characteristics of the lamp resulting in lamp colour shift and possible reduction in lamp survival.
