During operation, the bulb should be enclosed in a housing to prevent injury. Do not remove bulb from equipment until it has cooled. Protect the quartz arc tube when handling the lamp. Keep the arc lamp clean. Do not touch the quartz tube, the inside surface of the reflector, and the connecting wires.
Contamination can degrade lamp performance or cause premature failures.
If necessary, clean the lamp by wiping with a lint free towel or swab immersed in denatured alcohol. While HID bulbs last considerably longer than halogen bulbs, you should be aware of several characteristics that indicate that a bulb is approaching the end of its lifespan. Visual signs include blackening at the ends of the arc tube and electrode tip deterioration. Note that HID bulbs contain metals, including mercury, that are harmful to the environment. Please be responsible in securing proper disposal of an HID bulb.
