HID (High Intensity Discharger) CID (Compact Indium Discharge), CSI (Compact Source Iodide), xenon and most importantly for shooting purposes, HMI (Hydrargyrum, Medium Arc-length Iodide), are lamps containing special gases under pressure (some high, some low pressure) through which an electric arc is discharged to produce a highly efficient light s [..]

A lamp that produces light by discharging an electric arc through a mixture of gases and gaseous metals.

light source that provides illumination when an electrical charge is applied to gas particles in a glass tube. An example of this device is electronic flash.

Lamp in which the light is produced, directly or indirectly, by an electric discharge through a gas, a metal vapor, or a mixture of several gases and vapors.
