HID, High Intensity Discharge, (also known as Xenon) refers to lighting technology that relies on an electrical charge to ignite xenon gas in sealed bulbs, similar to the lightning phenomenon in the sky. HID lighting does not have a filament but instead creates light by igniting an electrical discharge between two electrodes in an air tight tiny quartz capsule filled with xenon gas. HID lighting are also called Xenon lighting, referring to the gas inside the hid bulbs.
