John, do you mean an amazing 6' (6 foot) long exposure box?

My small box is workable up to 21x24 inch, and has 12 20W 24 inch BLB
(blacklight black) tubes, not daylight (which are much lower in UV)
and is driven by Advance MH-2SP20-TP magnetic ballasts with a 90%
ballast factor (better starts and much higher output than the 50-60%
factor ballasts in those internet plans floating around) with a wood
frame and metal reflector/starter panel.

My big box is workable to 36x45 inch, and has 18 40W 48 inch BLB
tubes, driven by electronic ballasts with a ballast factor about 120%.
The nine ballasts are mounted in boxes four to a box (one box has
three ballasts unused), and can be removed from the printing frame and
used to power three eight bulb high CRI T-8 studio fluorescent
fixtures, or three eight bulb T-12 BLB fixtures for blacklight
photography...

Ciao!
