What is Xenon Light?

HID Xenon lamps do not have a filament like conventional halogen bulbs. Instead the light is created by an electrical discharge between two electrodes in an air tight tiny quartz capsule filled with xenon gas, mercury and metal halide salts. 

The light is created by striking and arc between 2 electrodes. The xenon lamp needs a starter for quick ignition and an electronic ballast to function correctly.

These light sources also produce a blue-white light that is safer than normal halogen bulbs because it produces a colour closer to natural daylight.
