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.
Step 1: Disconnect power to the fixture before installing or replacing the lamp.
Step 2: On the bottom of the fixture, turn the latch on the lamp door one-quarter turn and then
open the door.
Step 3: Remove the lamp holder assembly by turning the knurled knob counterclockwise to
release the lamp socket assembly.
Note:
Verify that the HPL lamp you intend to install is suitable for your facility’s voltage;
115-, 120-, 230-, and 240-volt HPL lamps are available.
See HPL Lamp Table, 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 attempting to change the
lamp.

Cleaning the Glass Lens and Reflector
Replace the lens if it contains visible damage such as cracks or deep scratches that may impair
their effectiveness.
The reflector is located behind the lamp. The lamp must be removed before cleaning the reflector.
Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. Isopropyl alcohol, distilled
water or a 50% mixture of each can be used to clean the lens and reflector.
Note:
Do not leave finger prints on the lens. Handle the lens with a soft, clean cloth.
Note:
The lens will not fit properly and will not function correctly if it is installed with the
stepped side facing the rear of the fixture.
WARNING:
Do not use ammonia-based or other harsh commercial cleaners. Clean lens
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.
