Halogen lamps

Halogen lamps also go by the names tungsten-halogen lamps and quartz-halogen lamps. These lamps have a tungsten filament that is sealed into a small space that is filled with a halogen gas (like bromine or iodine). Halogen lamps have longer lifetimes than incandescent lamps. They have a whiter color of light, too, as well as more brightness.

Halogen lamps are often used as desk lamps and reading lamps because they offer such excellent and bright task lighting. Your basic halogen lamps will last around 2000 hours, and this length of time is twice as long as your ordinary incandescent lamp can run. Do not touch the bulb of your quartz-halogen lamp because the grease on your finger can cause damage to the quartz envelope, and the lamp will not stay as bright for as long.
