Re: facial tanners for UV light?
Or build your own:
All you need are from 5 to 10 blacklight fluorescent bulbs (see Bulb Direct, Just Bulbs, Bulbtronic, et al on the Internet) and about $10 worth of lumber plus 2 sheets of plate glass for the "sandwich" (of negative & coated paper) and some mild carpentry skills to make your own light table. Several (including my own) are illustrated with instructions ("Light Carpentry") in Post-Factory #6. (My favorite is possibly Nick Makris's,
which ingeniously folds up for storage.)
But there are also many sources for plans... I forget the name of the prepared platinum paper (now defunct) that had a brochure with instructions for building your own, but Edwards (I think was the name) also provided plans for a setup, including fan. I think also somewhere in its history Bostick & Sullivan may have had a booklet or brochure with plans.
Bob Schramm used mercury vapor bulbs on his barn ceiling. "Exposures are long," he said, but "the coverage is large."
Not to forget sunlight, which some folks have all year round.
