When I was in elementary school, many of my teachers used overhead projectors with transparencies while going through a lesson. I want to do the same with our children as part of their home education. I was very surprised that none of the manufacturers made LED projectors, so I considered converting an existing projector.
I noticed that the kits on visiophare.org have much brighter lamps than the typical projector. Is this because they are being used in art projects that require projecting a greater distance? If I buy a projector with a 2000-lumen halogen lamp, do I need to get a brighter LED, or will a 2000-lumen LED assembly be just as functional?
