If you will send me your snail mail address, I think I can find plans
and list of materials for building your own fl light source; however,
if you have no expertise at wiring, you might not want to try it.
In my opinion, anyone who can do alt-process is bright enough to
build a light source. You can buy already constructed units but the
cost is four or five times the cost of materials if you build your
own.
