Homebrew PCBs

There are two basic types of home-use UV tubes, which look like
fluorescent tubes, but are varying shades of dark blue.  It has been
years since I looked at a lamp catalog, but as I remember, the types
with designation ending in  "/BLB" are "black light blue," have a clear
tube, produce reduced visible light, and cost much more than the "BL"
type, which have an internal fluorescent coating and emit more visible
light.  Assuming the BL type will work for you, they should save you
money in initial cost.
