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 opening and closing the rear castings (or covers) of luminaires and cleaning
reflectors. Any jarring can undo the optical alignment of the lamp.
Heat
On Forced Air Cooled Units
•
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 ten minutes before removing power
to the luminaires. This will provide enough time for the equipment fan to cool off the unit.
On Natural Convection Cooled Units
•
When lamps are lit, the interior and exterior heatsink of the luminaires becomes very hot.
Naturally convection cooled units require longer to fully cool before being handled. Users should
wait until the unit is cool to the touch before servicing or handling.
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.
•
If system will be unattended for more than two hours, luminaire lamps should be doused. Standby
mode should not be used for more than two hours.
•
When the lamp is struck, the luminaire should be maintained in a horizontal position when not in
use.
