| Iv also found yet another pretty big problem w/ ur projectors (hell these things are awesome though) i was looking at once today...and noticed soemthing "How come the shade of light from the light THROUGH the glass top isnt the same shade as when u look at the bulb through those side vents....THE GLASS ITSELF. OVERHEAD PROJECTOR GLASS ISNT PURE. Look at the glass at side angle...see the green? That denotes impurities. These impurities will degrade the light quality coming from the bulb, this is why the final image color wont be as great, even on a pure white wall. What to do? I dont know where to find pure glass, but i know the process to make it (used for making fiber optic glass) is more expensive...and i dunno where u can find it in such a size as needed. Hope this helps some of ur people's off-white, white color problems
