dump the IR glass for larger setups. I've been running my projector without it from the beginning and my brains haven't melted yet. Just make sure your fresnel setup is cool, they will warp and cause problem s if not taken care of. IR is necessary on smaller 7 inch setups because airflow is less. On larger setups a couple fans should be able to move enough air to keep things cool

Thanks for all your help.

I just saw that you live in Ottawa Newby..crazy. I live just over in Almonte. Where did you get your lens and how much did it cost?..find any stores in Ottawa that sell stuff like that. Im making a ps1 projector and im trying to persuade my dad to buy it over the net (80mm Triplet) but I was wondering if you saw any in Ottawa.

Thanks Rob

Hi Rob,

I bought my lens from DIYProjectorCompany. It's the 135mm long throw lens because I'm using a 15" LCD and I wanted the projector to be far enough from the wall. It's $120 US. The only thing I could find so far in Ottawa was a 400watt MH light at Home Depot but no ballist and the Lexon also from Home Depot. If any one knows where I can find a mogul base and ballist in Ottawa I'd sure like to know because DYIProjectorCompany is having problems getting the 250W light I ordered 01/11/06 and as others told me, I'd be better with the 400watt. I know Alan is trying but man, I'm getting anxious. I think the price there is excellent for the 80mm lens and that should be good for you.

Thanks Rob. I have a 500 Watt one from Canadian Tire but it gets way to hot.

Like people are syaing I think with 250W you'll need a good reflector to get a viewable image in the dark.

Currently with no reflector and a 400W lamp my image isn't that bright, although perfectly viewable in low light levels.

I haven't used IR glass, just some UV reflective polycarbonate which attenuates anything below 390nm.

Its been running for 100 hours now with no overheating problems or yellowing.

Thanks for the info goodbyeqti.

I hope the reflector will do the job.
