Homebrew PCBs

Hi Jeff,

I use a "Bright Lab Jr." 11W red bulb (#35110).  They are quite expensive today, about $19 list: http://www.cpmdelta1.com/safelights.htm

I actually prefer the ones that are red glass or painted on the inside, but lost mine many years ago.  I don't think a few scratches on the bulb will affect what you are doing.

I got mine at a photography store.  You will probably need a store that has supplies for black and white photography.
