Removal Procedure

    Caution: Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:

       • Turn off the lamp switch and allow the bulb to cool before changing the bulb.
       • Leave the lamp switch OFF until the bulb change is complete.
       • Always wear eye protection when changing a halogen bulb.
       • Handle the bulb only by its base. Avoid touching the glass.
       • Keep dirt and moisture off the bulb.
       • Properly dispose of the used bulb.
       • Keep halogen bulbs out of the reach of children.
