Well, what is the projector? For the most part it's probably a bad idea. One exception is that if you have projectors that use ordinary incandescent lamps, replacing those with halogen lamps of the same input power and adjusting the condenser and mirror assemblies can give you added brightness safely.
But if you have a 24V/250W lamp like the FJL lamp used in the Bauer classroom projectors, you already have about the brightest lamp you're going to get with that input power. Have you considered upgrading to a brighter projector? There are plenty of the Bell and Howell 500-series projectors out there and they are bright and fairly light on film. The 300-series are even lighter on film although more bulky. Avoid the auto-thread 500-series ones, though. --scott _______________________________________________ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
