Do not use lamps other than the HID in Source Four XT fixtures. Use of lamps
other than HID will void UL/cUL safety compliance and your warranty.
This fixture must be grounded.
The fixture is sold for either 120V or 220V, 230V (50Hz), 240V, 277V to match the
power supply. Verify that the lamp and ballast voltage requirements matches your
power supply. Connecting the fixture to the wrong voltage voids the

A lamp must be installed before you use the fixture. The lamp can be replaced without affecting the
focus.
WARNING:
WARNING:
Note:
Step 1:Ensure power has been disconnected and the lamp is cool before replacing the lamp.
Step 2:Loosen the screw securing the ballast.
Do not replace the lamp when it is raining or snowing. Do not stand in water
while replacing the lamp. Failure to follow this warning can result in serious
injury or death.
Disconnect power and let the lamp cool before replacing.
Verify that the HID lamp you intend to install is suitable for your fixture’s ballast.
See Lamp and Ballast Information, page 2. Operating HID lamps above their rated
voltage reduces lamp life and can cause premature lamp failure.
The facility’s voltage must match the voltage of the fixture and its ballast.
Figure-2 Ballast and Reflector Housing Base on the Back of the Fixture.
Step 3:Rotate the reflector housing to reveal the lamp cap.
Step 4:Loosen the four screws of the lamp cap.
The screws are captive so they will stay in the cap.
Step 5:Pull the lamp assembly straight out of the fixture.
Step 6:Carefully pull the old lamp out of the ceramic base.
Step 7:Holding it by the base, remove the new HID lamp from its box.

CAUTION:
Use caution when installing or replacing any lamp.
When installing or replacing lamp, be sure to point the lamp away from your face
and away from others before inserting it firmly into the assembly.
This may prevent injuries if the lamp should break.
Note:
To avoid premature lamp failure, do not touch the lamp glass. If you do, clean it
carefully with isopropyl alcohol and a clean lint-free cloth. Allow to dry before
operation.
Step 8:Align the flat sides of the lamp base with the lamp retaining clips on both sides of the
socket.
Figure-3 Inserting the Lamp into the Lamp Housing.
Step 9:Push down on the lamp base until the lamp seats firmly.
When properly installed, the base of the lamp will be secured by the lamp retaining clips.
CAUTION:
Improperly installed lamps cause premature lamp failure and socket problems.
Step 10: Reinstall the lamp assembly by aligning the lamp cap with the fixture.
Ensure the wire is pushed aside and not touching the lamp.
Step 11: Tighten the screws in a zig-zag pattern.

Focusing the Beam
Two internal lenses control the size and focus of the light beam. Each lens is mounted in frames
and these frames slide along the rails. The lens frames are secured in the desired location with two
knurled thumb screws.
•The field lens is nearest the lamp and controls the width of the beam.
•The focus lens is furthermost from the lamp and controls the focus of the beam.

WARNING:
Step 1:Remove the barrel as described in Removing and Installing the Barrel, page 7.
Step 2:Turn the Source Four XT on and aim it at a flat surface.
Step 3:Pull the shutters outward so that the aperture is fully open. Refer to Adjusting Shutters,

Pattern holder slots
The beam can be shaped using patterns and the shutters. The beam can also be colored with
colored glass in the pattern holder.
Note:
Pattern and Color Projection
The two pattern holder slots are inside the fixture and immediately in front of the shutters. The
holder slots accommodate B-size and glass pattern holders. The holder holds 2.5 and 2.75 inch
diameter patterns. One pattern holder for steel patterns is supplied with the fixture. Additional glass
or steel pattern holders are available from ETC.
The projected beam is the inverse of the inserted patterns and shutter
adjustments. That is, for a pattern to be projected right side up, it is inserted upside
down and backwards. Likewise, moving a shutter affects its opposite image.

Adjusting Shutters
Use the shutters to shape the light beam. For example, you may want to use them to block the light
from falling on part of a building. Or you may want to frame a sign. The shutters are held in place
by a spring shutter retention system. You do not need to tighten or loosen the screws to make
adjustments.
Step 1:Remove the barrel as described in Removing and Installing the Barrel, page 7.
Step 2:Turn the Source Four XT on and aim it at the structure you are illuminating.
Step 3:Pull the shutters outward so that the aperture is fully open.

Step 4:Use the tabs on the shutters to move them to block the beam as needed.
Keep in mind that the blocking is reversed.
Step 5:Reinstall the barrel.

WARNING:
Replace lenses if they contain visible damage (cracks or deep scratches) that may impair their
effectiveness.
Do not use ammonia-based or other harsh commercial cleaners. Clean lens
and reflector only as directed.
Commercially available glass cleaning agents should be avoided as they
may contain ammonia, other harsh chemical detergents or abrasive agents.
These cleaners may damage the glass surface and the Anti-Reflective
coatings. Do not immerse or soak the glass in any cleaning solution.
Cleaning Glass Lenses
