You can buy unshielded UV tubes for aquariums and such, I believe Phillips makes these in various lengths and you don't need a ballast. You can place them in any TL tube box and they work well for me, I've done Gum prints, salt prints and Cyanotypes with them, no problems at all.
If you need a type number or so let me know, I can look it up on the tubes.
Hey thanks for the advice! I did a search on the Internet and found a few. I'm going for the Phillips Actinic UV tubes.
