I built a UV printer myself, a while ago. I am not sure the specific GE F15T8 bulb is what you are looking. It would certainly expose but the speed is crucial. I cannot seem to find its specifications about the wave length it produces. If you can confirm that the bulbs produce peak output around 350- 370nm then they would be a good choice. BL is blacklight but It would be better if you can confirm its specifications.
An old thread on the subject I asked about the bulb, http://www.apug.org/forums/forum42/9...rinting-2.html
I used sylvania brand F24T? (8 or 12 I can't confirm now) BL368 bulbs 20W each ten in total. BL368 / BL350 / BL365 are the codes of the bulbs with suitable wave lengths.
From my experience, it is going to be a cable mess, I used 5 dual ballasts to power box. If you are going to use a single ballast, wrong connection means no power to all.
If you use more than one ballast, you can troubleshoot easily if there is a problem with ballasts or bulbs. I would prefer 5 ballasts over 1 ballast system.
Don't worry, you can't burn the house down.
I expose traditional Cyanotype for 7-8 mins, New Cyanotype 7 min, VBD 4:30, Salt 10-12 mins.
