Equipment Handling
Below are some basic tips and information on handling VL550 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 luminaires.
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 interiors of the luminaires become 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.
