Clean the Reflector
WARNING: Unplug the fixture and allow it to cool before you
clean the reflector.
To quickly clean the reflector, remove the lens tube and clean the dust
from the reflector with a blast of oil-free air. You may also wipe the
reflector with a clean lint-free cloth. If either method is not sufficient,
follow these steps.
1. To protect the lamp housing during cleaning, remove the LED lamp
housing by loosening the attachment screw and pulling the
housing straight out. (See image on page8 .)
2. Remove the barrel rotation knob located at the bottom of the
barrel. Use a Phillips screwdriver to remove the retaining bolt
located on top of the reflector housing.
3. Rotate the barrel 45° in either direction. Carefully remove the
barrel from the reflector housing.
4. Remove any dust with a blast of oil-free air or wipe with a clean,
lint-free cloth. You can use isopropyl alcohol, distilled water, or a
50%-50% mixture of each to clean the glass surface.
5. Insert the barrel into the reflector housing with the iris/pattern slot
on top. Align the triangles on both parts.
6. While gently pressing in, rotate the barrel 45° clockwise until it
sets into position, and then rotate the barrel counterclockwise 45°.
The barrel should be firmly attached and the triangles should be
aligned.
7. Reinstall the barrel rotation knob and tighten the retaining bolt.
8. Reinstall the LED lamp housing and tighten the attachment screw.
