What is HID?

HID stands for High Intensity Discharge. It refers to lighting technology that relies on an electrical charge to ignite xenon gas contained in a sealed bulb. The technology of HID automotive lamps is similar to that of common vapor-filled street lamps. HID lighting doesn't have a filament but instead creates light by igniting an arc between two electrodes. HID lights get their name from the intense white light produced by the electrical discharge. HID lamps are also called xenon lamps, referring to a gas inside the lamps. HID general lighting has been used for years in sports arenas and stadiums around the country.


Equalized controller system makes transient DC from 12V to 23KV, which light up Xenon and bring out electric arc. Compared to traditional theory of heating and lighting of filament, Xenon light is the crystal of modern science.
