HPL lamps HPL lamps are tungsten halogen lamps. Verify that the HPL lamp you use is suitable for the voltage at your facility. 230V and 240V HPL lamps are available. Operating HPL lamps above their rated voltage reduces lamp life and can cause premature lamp failure. WARNING! Do not use lamps other than the HPL in Source Four jr/Zoom fixtures. Use of lamps other than HPL will void UL and cUL safety conformity and warranty. Euro.

Cleaning lenses Caution! Change lenses if they become visibly damaged to the extent that their effectiveness is impaired, for example, by cracks or deep scratches. 1. Remove the lens assembly. (See Switching lens assemblies, above, steps 1-3.). 2. Remove safety screen. 3. Dampen a clean, lint-free cloth with vinegar or household ammonia. You may also use water, but it will leave spots which you may remove by polishing the lens gently with a clean, dry cloth.
