Hi Everyone! I have done some research on building a UV box, and things are a little more complicated here in Sweden, possibly a bit more expensive also... I have come up with some answers, and would like some more! I have found the 40W Philips Actinic 05 tube, it sells at about 17 USD each incl. tax (SEK 135). It measures 26 mm diameter and 590 mm long. For each tube I will need a holder that costs about 25 USD (200 SEK) and a ballast (reaktor in swedish) that costs about 14 USD (100 SEK). The outer dimensions of the holder including the tube 39 mm wide, 612 mm long and 78 mm high. If I put the holders side to side I will get a space between each tube of approx 15 mm, which seems good according to this site. If I put 6 of these tubes side to side I'll get about 220 by 550 mm of light. It juuuust covers an 8 by 10 print. The box will cost close to 450 USD (3500 SEK). I could get 7 tubes, equalling about 260 mm width, but that would add 80 USD (SEK 500) to the price. What would you do? The frame I'm waiting for is 9 by 11 inches (Dan Pelland Cherry) so I don't think I'm going to print bigger than that any time soon.
