GE – ConstantColor CMH PAR 30 – 70W E27 90V 15° 4700lm 830K WARM WHITE 80CRI/BALLAST REQUIRED – 41621/21683 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.

This is achieved by using the ceramic arc tube material from the Lucalox lamp, which minimizes 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.

Application areas: Road and Tunnel Street and Pedestrian Commercial areas
