Hi Dan,
id suggest asking on usenet rec.arts.theatre.stagecraft but this has started huge arguments in the recent past.
Anyway first thing is what you are after is Blacklight Blue lamps, blacklight is a generic term that includes lamps for tanning and fishtanks etc.
Fluorescent tubes, available in BLB from 6 inches to 4 feet these will all fit in standard fluro holders from a hardware store.
Couple of 4 ft tubes usually enough for a small stage to give that UV effect.
Compact Fluros like the energy savinb lamps,have seen them in BLB as 11w and 25w versions.
Mercury lamps,self ballasted,ie just screw in called MBTF,in 160w flavour usually,opr mercury lamps that need ballast from 60w to 400w,big ones will give you sunburn if you get too close.
Pro UV fittings from Wildfire and Nocturne very expensive but very good.
Avoid the blue coated incnadescnt lamps from novelty stores,inefficient and short lived.
Or gel theatre fixtures with Congo Blue,cant remeber gekl number offhand, wiorks on some fluro pigments.
UV pigments from variety of sources freom novelty store to pro theatre supply,even somenwashing powders with optical brightners will fluorsec.
