ABOUT LAMPS
1. To avoid any possibility of electric shock, disconnect the equipment from the power supply before removing and/or installing the lamp.
2. Articles fabricated from quartz/glass are inherently fragile and there is a remote possibility of a lamp shattering if subjected to mechanical shock, thermal shock or abrasion. Unless directed to do so, inserting the lamp into the holder by holding the bulb could cause mechanical breakage of the envelope/seal. For your safety, install by holding the lamp base and always use eye protection.
3. Oils/grease or handling of the quartz envelopes may contaminate the surface on operation and reduce performance. If the quartz is handled, clean before operation with a soft, clean, lint-free cloth moistened with methylated spirits (denatured alcohol).
4. Avoid improper operation of the lamp, e.g. operating the lamp at a voltage higher than the lamp is rated for or at improper burn angles. Non-observance may damage the lamp or equipment.
5. In operation, the lamp-
a) Develops a high internal pressure and could shatter
b) Develops a high surface temperature
c) May cause UV irritation to skin and eyes on prolonged direct
exposure
Use appropriate screening for people and surroundings. Avoid operation
in proximity to combustibles. Allow lamp to cool before attempting
replacement.
LENSES
During normal use, lenses collect a dirty film and should be cleaned for optimum performance. Cleaning can best be accomplished with soap and hot water or other glass cleaning solutions and a soft, lint-free cloth. Care should be taken so that the cleaning process does not leave a film on the surface of the lens, since the heat from the light beam will bond the film to the surface of the lens. Be careful not to remove the black painted rings on stepped lenses. Be careful not to mix the lenses during the cleaning process.
REFLECTORS
The reflectors of luminaires should be cleaned periodically as a dirt film may collect on their surfaces, sacrificing optimum performance. Before cleaning, the lamp should carefully be removed from the luminaire. Extreme caution should be taken not to scratch or deform the reflector in any way. To clean, use a soft, clean, lint-free cloth moistened with methylated spirits (denatured alcohol) and then polish with a dry, soft, clean, lint-free cloth.
MECHANICAL
Mechanical parts such as sliding lens tubes, lock down hardware, and clamps should be maintained using a commercial cleaner such as WD-40. Use commercial graphite for lubricating shutters and iris mechanisms.
ELECTRICAL
Inspect all wiring and connectors frequently for discoloration, loose connections, and cracking. Replace any questionable wires and/or connectors. Remove the lamp (power off, of course) and inspect base and pins for signs of arcing. Replace sockets if necessary.
