Most UV bang for your buck?
mimosatexas:
Stripping it down to just the bare essentials of a bulb outputting UV in the proper spectrum, what is the best bang for your buck?
Essentially, I'm looking for whatever weird chinese knockoff unbranded metal halide bulb would be the best "deal".
I don't care about an integrator, or shutter vs instant on, etc. All I am looking for is the absolute most powerful light source for the lowest cost that can produce a consistent amount of UV in a specific time (unlike the sun). Any ideas?

http://www.bulbamerica.com/ushio-mhl-1000-1-blacklight-metal-halide-bulb.html. This is what I am using. Has the correct spectrum for photopolymer. I took a old national exposure unit built a manual metal shutter and a fan for the bulb.
mimosatexas:
Thanks for the link. Finding 1k units for dirt cheap is pretty easy. I was hoping someone might have a source for 3k or 5k bulbs and ballasts.

I can find 3K and 5k bulbs. Ushio has plenty but no one seems to have the ballast. I have called several light supply companies. I was wondering if they could be hooked in parallel.
The biggest I have found is 1500w and 2000w. I would be interested if anyone has a source for a 3000w or 5000w ballast.

Here is a 5000w.

Olec is a good source of power for 5k bulbs
