Warning!

G

Keep bulbs out of reach of children.

Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing 
a bulb.

Halogen lamps contain pressurized gas. A 
bulb can explode if you:

앫

touch or move it when hot

앫

drop the bulb

앫

scratch the bulb

Wear eye and hand protection.

Because of high voltage in xenon lamps, it is 
dangerous to replace the bulb or repair the 
lamp and its components. We recommend 
that you have such work done by a qualified 
technician.
