I've no experience but wonder if your best bet isn't a super actinic
fluorescent source. You can see the spectral distribution in this Philips
data sheet for the TL-K 40W/03 SLV http://tinyurl.com/yvj6q7. It has a main
output peak at around 420 nm, which drops to a much lower output at 480 nm.
There are instructions for making a UV source for use in alternative
photographic printing processes at http://tinyurl.com/24wom6; you could
probably adapt it to your needs.

Subject: [PSCI-COM] fluorescence
Has anyone got experience in demonstrating fluorescence as part of a
public display? I'm wanting to display trichomes (leaf glands) that
fluoresce under violet light (420nm) and emit blue/green light (about 480nm)
and looking for suitable (cheap and sturdy) light sources or filters,
Elspeth
