4. Installing the lamp
Always replace the lamp if it becomes damaged or deformed. Verify that the lamp you use is suitable
for the electronic power at your facility.
Caution! Operating lamps above or below their rated voltage reduces lamp life and can cause
premature lamp failure.
1. Disconnect the unit from power before installing the lamp.
Warning! Let lamp cool before changing.
2. Loosen the knurled bolt on the back of the lamp housing and pull the housing straight out from
the back of the fixture.
3. Remove the lamp from its box,
holding it by the base.
Note: to avoid premature lamp failure, do not touch the lamp during installation, clean it
carefully with rubbing alcohol and a clean, lint-free cloth before operation.
4. Line up the flat sides of the lamp base with the brackets on either side of the socket. Figure 2
5. Push down on the lamp base until the lamp is firmly seated. Make sure that the lamp is fully
seated, with the bottom of the lamp heat sink flush to the lamp housing casting.
Caution: Improperly installed lamps cause premature lamp failure and socket
problems.
6. To reinstall the lamp housing, center it on the reflector and the bolt hole, then tighten the
knurled bolt to secure the lamp housing in place.
