Tungsram 20W Constant Color E27 PAR20 High Int Disch Bulb 1000lm EEC-A Ref26481 Up to 10 Day Leadtime

Tungsram 20W Constant Color E27 PAR20 High Int Disch Bulb 1000lm EEC-A Ref26481 Up to 10 Day Leadtime

ConstantColor CMH lamps combine the HPS technology (providing stability, efficiency & uniformity) and the Metal Halide Technology (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. Light Bulbs GBP 125245
