Equipment Handling
Below are some basic tips and information on handling luminaires and their associated components.
Locations/Use
VARI
❋
LITE luminaires are designed for dry locations only. Exposure to rain or moisture (including,
but not limited to, fog machines, misters, etc.,) may damage luminaire.
Lamps
Servicing
• When handling a lamp, hold it by the ceramic base while wearing cotton gloves or finger cots. Do
not touch the glass envelope (bulb). If you touch the glass with bare fingers, immediately wipe off
any fingerprints with isopropyl alcohol.
• Use care when removing and replacing covers of luminaire and cleaning reflectors. Any jarring
can undo the optical alignment of the lamp.
• Hot Lamp. Luminaire must remain powered on for 5 minutes after dousing lamp. Do not open for
5 minutes after switching off. Lampe chaude. Le luminaire doit rester en marche pendant 5
minutes après avoir éteindre la lampe. Ne pas ouvrir pendant 5 minutes après la coupure.
• Risk of exposure to excessive ultraviolet radiation. Do not operate without complete lamp
enclosure in place or when lens is damaged. Risque d’exposition aux rayonnements ultraviolets
excessifs. Ne pas faire fonctionner sans le boîtier complet de lampe mis en place ou lorsque
l’objectif est endommagé.
Heat
When lamps are lit, the interior of the luminaires becomes very hot. To aid in the airflow circulation
within the luminaires, after dousing the lamps, wait 5 minutes before removing power to the
luminaires. This will provide enough time for the equipment fan to cool off the unit. Users should wait
until the unit is cool to the touch before servicing or handling.
Note: Also, refer to “Fixture Shutdown” on page 41 for additional information.
Lamp Life
• When operating arc lamps, allow luminaires to operate for at least 3 minutes. It takes about 3
minutes for the fill components (mercury and halogen-metal compounds) in the lamp tubes to
vaporize completely. If the lamps are switched off earlier than 3 minutes, the fill components are
partially vaporized. The inadequately vaporized fill components and the electrode material
(tungsten) are deposited in the areas of the lamp tubes that have remained cool. As a result, the
lamp tubes blacken prematurely and reduce the service life of the lamps.
