Discharge Lamp
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), ...
-Discharge lamp - 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.
xenon
colorless, orderless, gas used in a gas discharge lamp to produce white light.
xenon lamp
a light source containing xenon gas; usually operated as a pulsed light source, as in a strobe lamp.
Emission can be spontaneous, as in light-emitting diodes, gas discharge lamps (such as neon lamps and neon signs, mercury-vapor lamps, etc.), and flames (light from the hot gas itself-so, for example, ...
5-inch square plastic disk used to store data or images. Not widely used anymore as their storage capacity is limited. Fluorescent The illumination produced from a gas-discharge lamp or tube is called fluorescent light. Find out more.
Different electronic flashes may have more complex circuitry than this, but most work in the same basic way. It's simply a matter of boosting battery voltage to trigger a small gas discharge lamp.
