I did not see the original question but if you are looking for the short
wavelength UV tubes for EPROM erasure, check with any moderate electrical
or lighting supply house and ask for a "germicidal lamp" as used by 
barbers.  They come in several sizes to fit standard fluorscent sockets.
I bought the 12 watt bulb that is about a foot long for about 15 bux.
I mounted a bare fixture in a piece of rain guttering.  I put the Eproms
in a piece of black foam and place the guttering upside down over the things.
This lamp will clear 27256's in about a minute.

If you are looking for "black lights", the long wavelength lamps with
the purple coating, most any gag-gift shop in the malls (Spencers, etc)
carry them.
