6. Fixture Cleaning
The cleaning of internal and external optical lenses and/or mirrors must be carried out
periodically to optimize light output. Cleaning frequency depends on the environment in
which the fixture operates: damp, smoky or particularly dirty surrounding can cause greater
accumulation of dirt on the unit’s optics.
y Clean with soft cloth using normal glass cleaning fluid.
y Always dry the parts carefully.
y Clean the external optics at least every 20 days. Clean the internal optics at least every
30/60 days.
Fresnel Lens:
Clean the lens with neutral soap and water, and then dry it with soft cloth. Be aware that
alcohol or other detergent could cause damage to lens. Please note the lens would be burnt
yellow or cracked after three-month use of average 8 hours per day, which can reduce the
output in some degree. The lens is consumable with a warranty of three months only.
Please change with genuinely new lens when necessary.
