Couple quick questions:

- I understand the use of black light UV bulbs. Do standard fluorescent put out enough UV to be useful? Or just stick with blacklights (or specially made UV fluorescent sources)?

- For the box, is the reflecting material important? I see some people use white. Does something like aluminum foil change UV reflectivity for better or worse?

- Do you just leave your light source "on" and slide a print under to keep things consistant? Or do y'all use "instant on" of the spirals and call it good?
