Halogen ceiling lights are powered by halogen bulbs. Halogen bulbs are light bulbs that use halogen gas to carry the tungsten of a light bulb back to the filament so the bulb lasts longer. The process for changing halogen light bulbs is basically the same as that of changing any ceiling light except that you should never touch a halogen bulb with your bare fingers. The oil on your fingers can cause weak spots on the bulb, which can lead to bulb failure or even a bulb explosion.
Turn off the power source to the halogen ceiling light. Allow the bulb to cool completely before changing it---halogen bulbs operate at a much higher temperature than regular bulbs. Position a ladder, stool or chair beneath the halogen ceiling light.
Remove the covering to the halogen ceiling light. Remove any screws connecting the covering to the light fixture, and place them in your pocket or somewhere where they won't get lost. Lay the covering aside.
Grasp the halogen light bulb firmly, using gloves or a cloth. Turn it counterclockwise until it unscrews from the light source.
Discard the used halogen light bulb. Hold the replacement halogen bulb with a soft cloth or gloves, and position the replacement halogen light bulb in the light source. Turn it clockwise until it is screwed firmly into the light source.
Replace the covering to the halogen ceiling light. Replace any screws holding the fixture to the light source.
Never insert your fingers into a light source.
