Changing and Adjusting the Lamp
The QXL™ 750/77 lamp is remarkably easy to replace. No tools are required and the lamp
is accessible from the exterior of the head. Once the lamp is turned to the unlocked position,
power is disconnected from the lamp. Two QXL lamps are available.
W A R N I N G :
The QXL lamp gets very hot during operation and remains hot for a time
after being dimmed out. To ensure that you do not burn your fingers on the
lamp base, always use gloves when removing a lamp from the Source Four
Revolution fixture.
W A R N I N G :
RISK OF ELECTRIC SHOCK! Do not place objects other than a QXL lamp in
the Source Four Revolution lamp socket.
C A U T I O N :
Do not touch the glass envelope of the QXL lamp. Oils and residue left on the
envelope can cause premature failure of the lamp. If the envelope is touched, clean
it with rubbing alcohol and a soft cloth before installing the lamp in the fixture.
Replacing the QXL lamp:
Step 1:
Power-down the fixture and disconnect the AC input cable. See
Step 2:
Using gloves, grab the lamp base and turn it 1/4 turn counter-clockwise to
disconnect the lamp.
Step 3:
Pull the lamp straight out of the head.
Step 4:
Install the replacement lamp, aligning the tabs in the lamp base with the slots in
the socket.
Step 5:
Turn the replacement lamp 1/4 turn clockwise until the lamp is seated and the
lamp base appears parallel to the horizontal center-line of the head.
