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.
N o t e :
Do not leave finger prints on the lens. Handle the lens with a soft, clean cloth.
N o t e :
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.
W A R N I N G :
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.
