I just made a pretty sick exposure unit...but the only problem now is to see if these bulbs are going to work well...I have 6 f20t12bl..is this going to work...because if not i need to return them..i know there are probably better ones out there but i just want to know if these will do the job. Thanks guys

Oh yea and how long should i expose the screens or at lease a rough estimate if these bulbs will work?

And just what is a f20t12bl?

It should be an unfiltered T12 black light tube.

Yes these bulbs will work...it what I use in my light box......my bulbs are blue in color..but I think your bulbs should be white.....but they are unfiltered black lights....I would start at 5 minutes and put a step wedge test strip on to pinpoint the correct time ...

f= flourecent
20 = 20 watt
t12 = bulb size the higher the number the larger the bulb...most are going to t8's which are a smaller diameter bulb..same watt's.
bl = black light(some say blb, which means black light blue)
