Quote from: Gilligan on October 24, 2013, 07:20:43 PMI heard that German machine used a DLP setup for the light source. That seems to make sense to me.Does look like it could be a projector, but a laser with a scanning mirror array could look just like that as well in a video. I think the question is what DLP stands for--digital light projection, or process. Any tech docs in English?

LED for reg film positives, w glass and vacuum?http://www.mrprint.com/en/Screen%20Exposure%20Units%20&%20CTS%20Systems/Screen%20Exposure%20Systems/Screen%20Printing%20Exposure%20Units/STARLIGHT%20UV%20LED%20Screen%20Exposure%20System

I think the question is what DLP stands for--digital light projection, or process. Any tech docs in English? I talked to them in Orland last week. It uses a small MH bulb that is then sent to the screen by mirrors (DLP). The bulb is good for thousand hours (100 days of 10 hours per day) and it costs $3k to replace!!! pierre
I'm not being critical here, I'm just asking a question because honestly I really don't know. The cost of a good LED bulb...the ones I have looked at to put on my truck range in price drastically from one manufacturer to another, these are light bars that's all the rage in the offroad vehicle community. They are reasonably priced units, encased in rugged enclosures to stand up to a lot of abuse. I'm thinking there are more bulbs needed in an exposure unit but the enclosure material would be cheaper and at the very least, not more expensive even though there is more of it. I've seen some 50" light bars like this for a decent chunk of change.http://www.xtralights.com/50-e-series-flood-light-bar-white-single.aspx?utm_source=GoogleShopping&utm_medium=organic&gclid=CNTGrpeyxLoCFQto7AodPGYARAI'd like to know, are the LED's needed for our exposure units significantly more expensive than the ones going into the offroad light bars like above? There are light bars this size and with similar specs for 1/3 of the cost and the Rigid seems to be one of the more expensive units. I realize they may be more specialized to hit the spectrum that we need, but does the added specialization raise the price of a bulb by a huge margin?I realize the people that can answer these questions probably aren't participating in this forum and most of us don't know exactly what bulb is going into these expo units nor what they cost, but I though maybe someone might have some knowledge to throw out here.
One of the biggest questions I had was answered in that there are 960 LED's on one unit. That's significantly more than I had thought would be there. I don't know exactly how many bulbs I saw on the Vastex unit I tested, I should have looked more carefully but I'm 100% certain there wasn't 960.
