I was thinking of making a new UV exposure box. Got rid of my old one
years ago when I was in a down sizing mood.

Been looking for UV bulb sources. I think my old unit used F15T8BL
tubes but not sure of the number.

Looking on ebay I see a lot of low cost nail curing lamps and nail
curing units. One add has 4 9W U shaped CF style UV lamps for $8.49
(item # 310199835791). Then you can get an entire nail unit for about
$35 and get 4 bulbs, balasts and lamp sockets. I think 4 bulbs would
make a nice 5 x7 or 6x8 exposure unit.

Has anyone ever tried these bulbs or one of the units on PCB resist?

I was thinking of using an array of UV led's but this may be easier and
provide more power.
