Lamp Information 3
Installing and Replacing the Lamp
A lamp must be installed before you use the fixture.
Figure 2: Lamp door on bottom of the fixture
1: Disconnect power to the fixture before installing or replacing the lamp.
2: On the bottom of the fixture, turn the latch on the lamp door one quarter-turn and then open
the door.
3: Remove the lamp holder assembly by turning the knurled knob counterclockwise to release the
lamp socket assembly.
4: Twist the lamp socket assembly counterclockwise one quarter-turn and remove from the fixture.
Figure 3: Remove lamp with quarter-turn counterclockwise
Note:
Verify that the HPL lamp you intend to install is suitable for your facility’s voltage;
115V, 120V, 230V, and 240V HPL lamps are available. See HPL Lamp Table on
page 2. Operating HPL lamps above their rated voltage reduces lamp life and can
cause premature lamp failure.
WARNING: Unplug the fixture and allow it to cool down before changing the lamp.
CAUTION:
The socket assembly remains connected to the fixture by means of its
electrical leads. Do not pull the wired assembly or place undue stress on it.

5: If replacing a lamp, carefully remove the old lamp from the lamp socket assembly.
6: Holding the new HPL lamp by the base, remove it from its box.
7: Align the flat sides of the lamp base with the retention brackets on either side of the socket in
the lamp holder assembly as shown in
Figure 3 .
8: Push down on the lamp base until the lamp seats firmly. When properly installed, the top of the
lamp’s base will be even with the top edges of the retention brackets.
9: Reinstall the lamp holder assembly into its socket in the fixture so that the arrow points towards
the “unlock” icon on the socket.
10: Turn the lamp holder assembly clockwise one quarter-turn so that the arrow points to the “lock”
icon.
11: Turn the knurled knob clockwise to secure the lamp holder assembly.
12: Close the lamp housing door and turn the latch to secure the door.
CAUTION:
Use caution when installing or replacing any lamp.
When installing and 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.
CAUTION:
Improperly installed lamps and lamp holder assemblies can cause premature
lamp failure and socket problems.
