A halogen light bulb is a type of incandescent bulb filled with halogen gas. However, halogen bulbs burn longer and cleaner than regular incandescent bulbs. It is important to remember to never touch the glass portion of a halogen light bulb. Oils from your hands can weaken the bulb, shorten its life span and possibly even cause it to burst when it is turned on.
Dip the end of a small, lint-free cloth in rubbing alcohol.
Wipe the glass portion of the bulb with the cloth.
Wipe the bulb with a dry, lint-free cloth. Make sure the bulb is dry before installing it.
