Homebrew PCBs

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.
