High Intensity Discharge (HID) Light Bulbs

     Some people may ask about HID lights "What exactly are HID light bulbs?". High intensity discharge or HID light bulbs are different from standard halogen bulbs in that HID lights replace the filament of the light bulb with a capsule of gas High Intensity Discharge (HID) are lamps in which an arc passing between two electrodes in a pressurized tube causes various metallic additives to vaporize and release large amounts of light. The light in HID lights is emitted from the arc discharge between two electrodes. HID light bulbs require ballasts to operate, which supply proper voltage and control current. The amount of light produced by HID light bulbs is greater than any standard halogen bulbs, and HID light bulbs also consume less energy and last longer than those regular halogen bulbs.

     Three most popular types of HID light bulbs on the market are: Mercury Vapor, Metal Halide, and High Pressure Sodium.
