Definition:

High intensity Discharge lighting is light from a plasma discharge rather than a filament. 
The system involves a combined igniter and ballast to start the light and maintain the current, and certain gases and metal salts to create the light. 

Overall the system uses less energy than halogen lighting, while producing 4 times more light per watt.  HID lights are sometimes referred to as Xenon bulbs, due to the presence of Xenon gas between the electrodes. 

High Intensity Discharge Lights do not have a filament.  Instead light is created from an electrical discharge between two electrodes in a micro-environment of xenon gas and metal halide salts.  The light is emitted by an electrically energized gas -- a plasma discharge -- formed and sustained between the two electrodes.
