WRONG!  This is BACKWARDS.  Germicidal lamps are EXCEEDINGLY DANGEROUS.

They are GERMICIDAL because they DESTROY CELLS.  Got it?  Repeat after me:
	If germicidal lamps did not destroy cells they would be useless.
	If germicidal lamps did not destroy cells they would be useless.
	If germicidal lamps did not destroy cells they would be useless.

Someone said "but I have seen germicidal lamps in barbershops." Germicidal
lamps are often placed behind a glass panel.  Glass filters out short wave
uv, passing the long wave.  The blue you see is the long wave radiation
passing through the glass.  This is not overly harmful provided you don't
get too much exposure.  Eprom erasers use short wave UV and thus REQUIRE
filters.  Be very careful -- the cells you save may be your own.
