Thats exactly what you do buddy 🙂

k thnx helps out now i can look for the right fresnel ^__^ happy day

o and i get an email from Allen at diyprojectorcompany.com, he said there is a back order on several parts including the lights, which is was i ordered....i emailed him back asking if he knew for sure if i would or wouldn't get the parts before April 1st....if its a no i gota find new parts
 
Please let me know if you do find another light source. I also receieved the backorder email from diyprojectorcompany. You would think he would update his site to tell us it was on backorder before we ordered....Oh well, at least he did send us a email...
 
Sure. Here is an electronic ballast. Here is a magnetic ballast and here is another. Here is a magnetic ballast from Businesslights.com which is a site I recently ordered from. Good communication and not stocked items were shipped within a week. I think they were also the cheapest including shipping by a dollar or two.

Of course, you may like eBay, in which case here is a good seller with an Icecap 250W electronic ballast with a buy-it-now price shipped for $125, which is a fair deal.

If you've got the cash you'll be happier with an electronic ballast IMHO. Hope I've helped.😉

The DIY Projector Comapny store has Fresnell lenses in 7"

http://www.diyprojectorcompany.com/catalog/index.php

I do have a question regarding focal lengths though. I attached a drawing(excuse the crudeness.) Am I right that you want to match the focal length of the Fresnell with the "Effective" focal length of the lens? And the rear focal length ends up being shorter?

If that's how it is, has anyone tried the 80mm lens from DIY Projector Company? Is that 330mm effective length? What is the rear focal length?

Thanks!


$45 for a 7inch frensel thats only 92% transmisive? Kinda steep.

You can get the front surface mirror he has and what the DBG carries from stained glass wharehouse for $29 for 2 12"x16" sheets lol, and its cr@p. Ive tried it, cruser sent me some ages ago.
