- Turn off the halogen downlight and give it plenty of time to cool off. Halogen lights operate at very high temperatures.
- Set the step ladder beneath the halogen downlight. Make sure the ladder is locked in position and secure before climbing up.
- Remove the metal spring from the downlight. Some halogen downlights have a round metal spring that holds the bulb in place. Grip the tabs on the spring with a pair of pliers and squeeze them together until it pops out.
- Put on the gloves or use a cloth to handle the bulb. Oil from fingers can cause a halogen light to break due to uneven heating of the surface.
- Push down on the old bulb and turn it counterclockwise until it pops out from the fixture. Some downlights have a plastic clip that hangs down from the center of the light on wires. You may need to pull the bulb directly out.
- Locate the three-letter code on the metal base of the halogen bulb. Match this code to a new bulb when shopping or take the old bulb with you to make sure you get an exact replacement.
- Open the container with the new bulb and handle it with gloves or with a cloth. Climb back up the step ladder. Push the new bulb into the fixture and turn it clockwise to secure it or push directly into the plastic bulb connector. Replace the spring clip if necessary by squeezing the tabs together and popping it back into place.
- Test the new bulb by turning on the light.
