Re: super-actinic bulbs
Judy and all, My UV light setup which I have discussed on the list before,
was the product of a few converversations with Bill Laven who may have
dropped from the list recently. There are 4 bulbs; 2', 40W, Super Actinic
which are install on 2-1/4" centers and the image rests at approximately 1"
above the tubes.
The exposure times I use range from 3-6 minutes. I do have a digital image
of the setup. Requests off list.
