Hello, I have 3 psone screens, so turning one into a projector seemed pretty cool.
I have 5" screen and 11"x8" freznels, so I'm trying to build the box to the freznel's size.
I have a page magnifier from a rip off ebay auction for a projector that measures roughly 13" (330mm) focal length. and a Staples page magnifier that measures roughly 15" (380mm) focal length.
And I bought the Lumelab 1002 S15 projection lens. (320mm) focal length.

I'm trying to make a test box, I don't have a light source.
Does anyone have a recomendation on a source I can use to test my measurements?
I'm pretty much affraid to go any further without getting some sort of confirmation
it's going to work for me.
If I get a 400w light setup and I don't get results, I'd assume I need new freznels, etc.
I'm not sure how much further money I want to put into this.

My second concern is the 400w bulbs. I don't like fire, I'm really not sure I want to take any risks in
that department. I'd be willing to go with a screen that can only be seen in a very dark room if it
gives my less likely risk of burning down the house.
