Subject: Re: [Homebrew_PCBs] UV Light Source for Exposing PCB's

Even better is to get some real flourescent UV bulbs. I got mine from a
local lighting supply house. I just looked for light bulbs in the yellow
pages. The bulbs are F20T12/BL and cost me about $10 per tube when I bought
them last year. They are a 2' long bulb and go into a standard fixture that
I got at Home Depot. I added a 5 minute mechanical timer to control the
exposure.
