High Intensity Discharge (HID)

High Intensity Discharge (HID) lamps produce light from an electrical arc between electrodes in a quartz or fused alumina arc tube which is located inside the bulb envelope. The arc tube contains a gas mixture of argon and/or xenon and/or neon depending on the type of HID bulb. There are also metals inside the arc tube that evaporate when heated intensifying the visible light.
