Ceramic Metal Halide Lamp Supermini 20W and 35W GU6

Product information 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. Tungsram has now miniaturized this technology resulting in the CMH Supermini, highly efficient 20 and 35 Watt lamps with the light quality and colour stability associated with Ceramic Metal Halide, in a size comparable to tungsten halogen capsule lamps, thus offering new energy saving options to the lighting designer and end user. Features Application areas • Consistent colour over life Retail Office Hospitality Street and Pedestrian • Excellent colour uniformity lamp to lamp • Bright light – in a very compact size • Excellent colour rendition • High reliability due to 3 part design • Up to 87 Lumens per Watt (LPW) efficacy • Long Life • UV control • 35W available in two colour temperatures • Robust GU6.5 base DATA SHEET General Information 1 Measured in horizontal orientation on T4 quartz capsule, with thermocouple attached directly above the centre of the arc tube. 2 Measured on quartz capsule pinch, immediately above the GU6.5 ceramic cap.

The declared lamp life is the median life, which is when 50% of the lamps from a large sample batch would have failed. Lamp life in service will be affected by a number of parameters, such as supply voltage variation, switching cycle, operating position, mechanical vibration, luminaire design and control gear. The information is intended to be a practical guide for comparison with other lamp types. The determination of lamp replacement schedules will depend upon the acceptable reduction in illuminance and the relative costs of spot and group replacement. Note: The representative curves are taken in Vertical Base Up position. Life performance can greatly increase in Horizontal Burning position.

A common characteristic for all metal halide lamps is a reduction in light output and a slight increase in power consumption through life. Consequently there is an economic life at which lamp efficacy falls to a level when lamps should be replaced to restore design illumination levels. Where a quantity of lamps are installed within an area, consideration should given to a group lamp replacement programme to maintain uniform illumination levels. Curves represent operating conditions for an 11 hours per start switching cycle, but less frequent switching will improve lumen maintenance. Note: The representative curves are shown for Vertical Base-Up lamp orientation unless otherwise specified. Lumen maintenance performance improves when operated in the Horizontal burning position. Warm-up characteristics During the warm-up period immediately after starting, lamp temperature increases rapidly evaporating mercury and metal halide dose in the arc tube. Lamp electrical characteristics and light output stabilise in less than 4 minutes. During this period light output increases from zero to full output and colour approaches the final visual effect as each metallic element becomes vaporised. 40 20 0 60 80 100 0 2 4 6 8 10 12 Burning time (thousand hours) (%) of original CMH Supermini 35W 942 Burning time (thousand hours) (%) of original CMH Supermini 20W 830 0 20 40 60 80 100 0 246 8 10 12 40 20 0 60 80 100 0 2 4 6 8 10 Burning time (thousand hours) (%) of original CMH Supermini 35W 930 Typical warm-up CMH Supermini 20W 0 1 234 Time from switch-on (minutes) Time from switch-on (minutes) 140 160 120 100 80 60 40 20 0 140 160 120 100 80 60 40 20 0 0 1 2 3
