Halogen light bulbs produce a hotter, brighter but softer light than traditional incandescent bulbs. A halogen bulb will not screw into a traditional socket, so do not buy halogen bulbs unless you have halogen fixtures, and do not try to install halogen bulbs into traditional sockets. When installing a halogen light bulb you must take care to not touch the light bulb with your bare fingers. The oils from your hands can shorten the life of the bulb.
Allow the light to cool completely before you try to replace the bulb. Remove the protective cover over the halogen light socket. This may require you to remove screws with a screwdriver, or to grasp clips that hold the cover in place and pull the cover off.
Put on a protective glove. Grasp the halogen bulb by the bulb end and insert the bulb into the fixture. If you do not have gloves, you can use a non-linen cloth to handle the bulb.
Replace the protective cover and screw it back into place, if necessary.
