I have built a number of enlargers and tried several light box strategies including multi-lamps and single quartz lamps. If you don't want to go the cold-light route the indirect quartz light is by far the best. I used an old hair dryer mounted on the wall and ducted to the lamp head. You will be saving yourself a lot of grief in the weight and mass department by going for a foam core and duct tape lamp house. You will want anti-newton ring glass for the neg carrier and 3/16 plex, milk white difuser material available here: http://www.fpointinc.com/index3.htm btw I have had cold light lamps built for me at neon shops. They make a 8 x 10 (or two 4 x 10) tight, zig zag patterned lamp from 8mm white glass. If you run across a broken neon beer sign grab it up for later use as the transformer for the cold-light.
