Special Considerations for HID Lighting Systems
The light emitted from the HID arc tube is intense and appropriate
safety precautions relating to exposure protection are required. Metal
halide bulbs operate at very high temperatures and pressures. The glass
lamps should be handled with care giving special attention to the quartz
arc tube. The Halcyon HID light is a DC lamp; proper electrical wiring
polarity must be observed to prevent damage to the lamp. Only certified
Halcyon repair technicians are authorized to work on Halcyon products;
non-certified work voids your Halcyon warranty.
CAUTION: Ultraviolet, visible and infrared radiation is emitted from
metal halide lamps. Possible skin or eye irritation can result from
exposures exceeding 15 minutes. Do not stare at exposed lamp in
operation. During operation, the bulb should be enclosed in a housing
to prevent injury. Do not remove bulb from equipment until it has
cooled. Never handle the bulb when it is operating. Keep your face
away from the light head during ignition and operation.
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.
Any interaction with the bulb should be conducted
very carefully. Bulbs break easily when handled
improperly and are not covered by warranty.
While HID bulbs last considerably longer than
halogen bulbs, you should be aware of several
characteristics that indicate a bulb is approaching
the end of its lifespan. Initial symptoms of end-of-
life are characterized by low light output and/or intermittent starting.
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 arranging
for proper disposal of an HID bulb.
The bulb and ballast are sensitive to external operating temperature.
Although Halcyon's HID light doesn't generate the amount of heat of a
halogen light, it should be treated like any other dive light. The HID lamp
should only be operated while in the water, to provide proper cooling for
the lamp assembly. While transporting your HID light, please don't leave
the light in direct sunlight or in a car's interior on a hot day.
