Detailed Product Description

High intensity discharge light sources, similar to High Pressure Mercury Vapour lamps. These lamps produce light spectrum closest to sun light. These may be called man made sun light.The quartz arc tube contains mercury together with Sodium and Halides of Sodium, Thallium, Indium and Dysprosium. To obtain further improvements in colour halides of Rare Earth metals are used.The principle of operation is that each metallic vapour participating in the electric discharge produces its own colour spectrum covering entire visible range. Hence there is necessity to add multiple halides of metal to be called as Metal Halide Lamps or Multi Vapour Lamps.
