YASMINE JULMISSE LOOKS INTO WHAT’S BEHIND THOSE BRIGHTER BULBS. THESE ARE HID OR HIGH INTENSITY DISCHARGE LIGHTS. HALF THE LENS IS COVERED BECAUSE THE LIGHT IS SO BIG AND BROAD, THEY’VE TONED ...

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 ...

High intensity discharge (HID) is a general term for mercury, metal halide, and high-pressure sodium lamps. Mercury lamps operate at a relatively high pressure and temperature. Most of the light is ...

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.

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 ...
