High Intensity Discharge (HID) lamps are a type of arc lamp. An HID lamp is comprised of a "glass" arc tube filled with a gas and a metal salt. The tube is generally fitted with two tungsten electrodes. Current applied to the electrodes is initially conducted in an arc through the gas. This initial arc raises the temperature of the metal salt until it vaporizes. At this point, the arc is conducted by the vaporized salt, greatly increasing the light output and decreasing the electrical current consumed.

There are several types of HID lamps in current use:
Mercury-vapor
Metal-halide (MH)
Ceramic MH
Low Pressure Sodium-vapor
High Pressure Sodium-vapor
Xenon short-arc


Each chemistry offers a different mix of operating characteristics including light intensity, color temperature, color rendering index (CRI), energy efficiency, and lifespan. The "glass" from which the arc tube is made must withstand extremely high operating temperatures and is typically composed of translucent or transparent fused quartz or fused alumina.

HID means High Intensity Discharge and is a modern form of lighting in which a compact arc is used as the source of light. They are more efficient that halide lamps.


Is high intensity light the same spectrum as white light?

High intensity light refers to light that is exceptionally bright or luminous. White light, on the other hand, is a combination of all the colors in the visible spectrum. Therefore, while high intensity light can include white light, it can also refer to bright light of any color.
