What is HID Xenon?

   HID lamp (High-Intensity-Discharge) is the top product of the Metal halide lamp. Unlike Halogen lamps, HID lamps don’t have a filament but create light by the arc between two electrodes. There are distinctive metals contained in the arc tube: high-pressure Xenon (99.99%), mercur and metal halide. When starting voltage is applied to the electrodes from the ballast or igniter, an arc is formed between them. The arc activates the Xenon, which in turn ignites the metal halide. The result of this action is the emission of light energy. Due to the high pressures of HID lamp operation, these wavelengths are concentrated in the visible light spectrum. We can get the desired color temperature through changing the pressure of HID lamp or the proportion of the metal halide.
