CMH Single Ended G8.5 Product Information for OEMs 17th July, 2007 GE Consumer & Industrial Lighting ConstantColor™ CMH™ Ceramic Metal Halide Lamps Single Ended G8.5 Product Information 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. Features • Consistent colour over life • Good 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 Lumen per Watt (LPW) efficacy • Up to 15,000 Hr life • UV control • Colour temperatures 3000K, 4200K Single ended format Single ended Ceramic Metal Halide lamps are designed to provide symmetrical beam distribution using the axial configuration 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. Applications areas • Retail • Offices • Stage/Studio • Architectural lighting • Display Cabinet • Hotels Specification summary* Ordering Information Description Wattage Colour Product Code CMH20/T/UVC/U/830/G8.5 Plus 20 3000K 39858 CMH35/T/UVC/U/830/G8.5 Plus 35 3000K 43273 CMH35/TC/UVC/U/842/G8.5 35 4200K 26348 CMH70/TC/UVC/U/830/G8.5 Plus 70 3000K 43274 CMH70/T/UVC/U/942/G8.5 70 4200K 26349 General Units 20W 3000K 35W 3000K Plus 35W 4200K 70W 3000K Plus 70W 4200K Product code 39858 43273 26348 43274 26349 Nominal Wattage W 20 35 35 70 70 Format Single ended Bulb type T4.5 T4.5 T4.5 T4.5 T4.5 Bulb diameter mm 14.5 14.5 14.5 14.5 14.5 Bulb material UVC Quartz Bulb finish Clear Arc Gap mm 3.35 4.65 4.3 7.4 5.5 Base G8.5 G8.5 G8.5 G8.5 G8.5 Operating Conditions Burning position Universal Luminaire characteristics Enclosed Notes: 1) Lamp voltage in the luminaire should not increase by more than 5V when compared to lamp voltage in free air. 2) Ballast protection required, according to IEC61167. 3) 35W & 70W data is based on operation from a conventional magnetic ballast. Improved performance can be achieved using an electronic ballast. 4) 35W 4200K CMH lamp is based on operation from an electronic ballast. Lamps can run on conventional ballast with a small reduction in performance. 5) 20W designed for operation only from an electronic ballast.
