Some time ago (years now) I faced a similar question when I needed to work
on an old project with some UV erasable parts. LEDs certainly couldn't do
it then, and I don't think they can today. Other options included small gas
tubes sold for germicidal use. An exhaustive 12.5 seconds of googoling
finds these:

0K
http://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation
Which at least suggests things are still readily available.
Not that anybody cares, but my story ended by forcing the hardware upgrade
to a flash part so this became a non-issue.

Of course, you may be in the opposite situation - could you use an old UV
chip eraser?
