CAUTION
Use of the proper type of lamp is essential to the safe and proper operation of the FireLight. Do not
install any replacement lamps greater than 35 watts at 12 volts, or any lamps rated for other than 12
volt use. For general replacement purposes, use only the recommended 35 watt narrow beam MR-11
lamps meeting ANSI specification FTE, or 20 watt narrow beam MR-11 lamps meeting ANSI
specification FTB. Other lamp types, such as colored lamps may be acceptable, but for best results use
only narrow beam lamps. Never exceed the maximum lamp wattage of 35 watts.
Make certain the unit is not powered before installing a replacement lamp. Remove the replacement lamp
from its packaging, and confirm that it is a 12 volt FTE, FTB, or other suitable replacement type. Handle
only the outer edges of the reflector, do not touch the lamp capsule inside the reflector. Install the new
replacement lamp by aligning the body of the lamp to face straight away from the face of the socket, and the
lamp pins to align with the holes in the ceramic lamp socket. Press the lamp straight into the socket until it is
fully seated and centered to point straight away from the face of the socket and the lamp door. Do not twist
the lamp during installation or the lamp and socket could be damaged.
Before closing the lamp door, make sure that both latch knobs remain pulled out in the unlatched position.
The lamp door will not close if either of the latches is in the latched position. Some resistance may be felt as
the latches dock into the socket holes on the fixture, but if the door fails to close fully, check that both latch
pins are pulled out to the unlatched position. After the door is closed flush with the housing, push in on the
latch pins until they snap to the inner and locked position to secure the door. Reconnect the power cord if
disconnected, and apply power to the unit. Observe the fixture for normal operation, and make any aim or
focus adjustments needed for best operation.
Maintenance
The primary maintenance required by the fixture will be lamp replacement. Typical lamp life should be in
the range of 2000 hours with the standard 35 watt FTE lamps recommended. Longer lifetimes may be
obtained with specialty or lower wattage lamps, but the fixture output may be reduced when lower wattage
lamps are used. Colored lamps typically have shorter lifetimes than standard white replacements.
The two DC effect drive gearmotors installed in the unit are sealed and permanently lubricated, and should
not require maintenance over the lifetime of the fixture. Some minor leakage of oil from the motors may be
expected over time, but this is not an indication of motor failure, and is objectionable mainly because of the
dust it tends to capture inside the fixture. After prolonged operation, typically 15 to 20 thousand hours, the
gearmotors may fail to operate due to brush wear or contamination. Temporarily running an inoperative
motor at a high speed setting may clear off contaminated brushes and restore a motor to normal operation.
Worn out brushes will eventually require the installation of replacement effect drive motors.
Aside from lamp replacement, the only maintenance recommended is a periodic cleaning to remove dust
accumulation from the fixture. Convection heat will draw air through the fixture, and dust will eventually
build up outside and inside the fixture over time. Heavy accumulations of dust will reduce the fixture output,
and may eventually obstruct the airflow through the unit, resulting in increased temperatures and reduced
lamp lifetimes. Periodic cleaning with compressed air will remove most light dust contamination. Heavy
dust contamination may require removal of the fixture outer cover for more thorough cleaning using
compressed air, aided by a soft dry brush or tissue paper. Severe contamination by dust in combination with
water mist, fog, and oil or smoke fluid residue may require the use of a cleaning cloth or tissue dampened
with water, or a water based cleaner to thoroughly remove dirt from the interior and optical surfaces of the
fixture. Proper cleaning and a fresh lamp will generally restore the fixture to its original performance.
