I am pretty sure the type of lamp that works for erasing Eproms
and the Eprom cells in a PIC is a UV-A, not UV-B lamp.  The UV-A bulbs and
tubes (they come both ways), emit a shorter wavelength of light.  They are
also much more dangerous so watch out and don't watch them at all.

        The UV-A lamps actually ionize the air so you may notice an ozone
smell when you open the box after erasing Eproms.  The bulbs are, in fact,
called germicidal lamps and used to be popular in air conditioners and
clothes driers.
