Hello,

I am new to the science of DYS Projectors
I have a 410W 82V FXL Overhead projector and
a 8 inch stripped LCD

I have a dumb question.
The Overhead's stage glass is much wider than the LCD Panel.
If I move the light source closer to the Fresnel lenses to get the light pattern
closer to the size of the LCD panel will I get brighter light through the panel?

Thanks
Lyle

I would say no, you would dim the light. The light source is at the correct focal length of the fresnels as the are. Moving it closer will put the FL behind the bulb.

Hey, not to veer of topic, but can you tell me what are the specs for overhead projector bulbs in terms of lumens and life?

Edit: I just did some searching and I found some overhead projectors are around 2500 lumens - how are people able to get decent projections with such a low lumen light source?

410 watt 82V FXL
supposed to be up to 4000 lumens.
Bulb life is going to be short but I have bunch of bulbs

I knew better but I thought I would ask before wasting a bunch of time

Thanks
Lyle
