Ceramic Metal Halide
Several years ago, Ceramic Metal Halide (CMH) technology was introduced to the lighting industry. Like most new lighting technologies, it has taken some time for these great new lamps to be universally adopted, but today you can find them almost anywhere. CMH lamps were introduced to provide a high quality, energy efficient, alternative to incandescent and halogen light sources.
In order to accomplish this, the lamp technology had to solve many of the problems inherent in older style quartz metal halide lamps such as high lumen depreciation, low color rendition, and poor color consistency. We've all seen projects in which some of the metal halide lamps lookwhite, some blue, some pink, etc.
By contrast, CMH lamps offer high CRI(Color Rendering Index) values in the 80-90 range, color temperatures of 3000K or 4100K, and are guaranteed not to color shift more than +/- 200k over the rated lamp life. They also have improved lumen maintenance characteristics.
CMH lamps are available in ranges from 20 watts through 400 watts, and in most standard configurations including ED17, PAR20, PAR30, PAR38, and T6. One of the newest types is designed specifically as a direct lamp retrofit for 400 watt High Pressure Sodium lamps. This retrofit offers far better color quality without requiring the replacement of existing ballasts.
Perhaps the best opportunity for the use of CMH lamps is in retail spaces. Retail lightinggenerally requires point source accent lighting and high contrast ratios. Most retail lighting in the United States is still delivered by inefficient halogen track heads or recessed accent adjustable luminaires. We've already seen that CMH lamps may be effectively used in place of halogen sources for accent lighting. 35 watt PAR20 lamps and 70 watt PAR30 lamps are particularly effective at lighting merchandise when used in track heads or other accent luminaires. Many retailers throughout the country are moving to these sources to save electricity and radically reduce maintenance costs.
