HID bulbs are quite different from conventional halogen versions. The light source is an arc between electrodes, rather than a filament, and they run on higher voltages than conventional lamps.

They operate at relatively high pressures and temperatures. High intensity discharge (HID) is a general term for mercury, metal halide, and high-pressure sodium lamps. Mercury lamps operate at a ...

HID headlights "discharge" a powerful light beam by igniting high-pressure xenon gas. Unlike traditional vacuum-sealed or halogen headlights with filaments, HID headlights generate an arc between ...

Different lighting technology has its pros and cons. If you're looking for affordability, go with halogen; for brightness, choose xenon. LEDs provide efficiency and durability. Projector setups give ...
