Removal Procedure

   • 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.

Notice: Avoid touching the bulb or letting the bulb come in contact with anything damp. Oil from your skin or moisture on the bulb can cause the bulb to explode when the bulb is turned on. If either comes in contact with the bulb, clean the bulb with alcohol or a suitable degreaser and wipe the bulb dry.
