Special Cleaning and Care Instructions
The VL440 / VL770 / VL880 Spot Luminaires requires special care when it comes to cleaning front
and internal lens assemblies.
The following is a list of cleaning materials required to care for your VL440 / VL770 / VL880 Spot
Luminaires:
• Lint free lens tissue
• Lint free cotton swabs (for hard-to-reach spot cleaning)
• Lint or powder free gloves
• Reagent grade isopropyl alcohol
• A mild soap solution.
Reagent grade isopropyl alcohol is good to use on the VL440 / VL770 / VL880 Spot Luminaires optics
with anti-reflection coatings.
If the lens is still dirty after using isopropyl alcohol, for instance if fingerprints or oil is just
redistributed and not cleaned off the optic, then a mild soap and water solution can be used to gently
wash the lens. Repeat the cleaning with isopropyl alcohol to eliminate streaks and soap residue.
WARNING: Under no circumstances should ammonia-based cleaners or other harsh solvents be used
on or near the VL440 / VL770 / VL880 Spot Luminaires. These types of cleaners or solvents can
permanently damage the optics or housings of the fixture.
If you have any questions regarding the use or care of your VL440 / VL770 / VL880 Spot Luminaires,
