It takes only low UV to expose the photoresist used for PCBs. So a
blacklight will work, however, anything that gives off low UV will
work. Like plant grow lights, those slightly bluish lights you can
get even at the hardware store.

Hi,
Years ago I tried to locate a UV light to erase Eproms. I
got alot of bad info. The Blacklight for posters is not
the right wavelength. UV bulbs look like a clear florescent
light bulb. They used to come with a drop of mercury in them.
After
trying to buy one, I found one in a Tropical Fish store. They
are used in a Sterilizer. Water passes past the bulb and the
germs in the water are killed. Do not look at the light while
it is on!!! It may look like it is not bright but it can give
you welders flash! You will wake up 2 o'clock in the morning with
the feeling sand is in your eyes. Be careful!
