Casablanca builds the "world's finest ceiling fans," according to the company motto. Whether they are the finest may be a matter of opinion, but one cannot argue that Casablanca does not build high-quality ceiling fans. Casablanca ceiling fans use halogen bulbs; and a few extra precautions should be taken when changing the bulb.
Turn the light switch off before beginning. This will ensure your safety. Wait a few minutes to let the bulb cool off, if it was turned on recently. Halogen bulbs produce more heat than incandescent bulbs.
Turn the glass dome counterclockwise a few inches to move the the locking tabs away. Use a step ladder if necessary. Set the dome down in a safe place.
Twist the halogen bulb counterclockwise until it is unscrewed from the socket. Discard the bulb.
Insert the replacement halogen bulb. Hold the bulb by its base; don't hold it by the glass. Turn the bulb clockwise until it is secure.
Lift the glass dome into place. Turn the dome clockwise until the three locking tabs are aligned.
