Halogen light bulbs are incandescent lamps containing a halogen gas instead of an inert gas in the bulb. Halogen bulbs are more efficient, give higher quality lighting and have a longer rated life compared to ordinary in... More »

According to Union College, an incandescent light bulb operates by acting as the load in an electric circuit. The glass bulb contains a wire which heats up with electrical current, and the heat causes the wire to glow wh... More »
