Blacklighting a Room

Hello all,

A friend of mine had an idea to light a room with cold cathodes.  It turned out pretty well, however, I'd like to do mine with UV black lights.  Do any of you guys have experience with blacklighting a large room?  I"m thinking about daisy chaining a bunch of UV Cold Cathodes together but I feel like I'd need a shit ton and may be better off just getting a few big black light fixtures.  If anyone has ANY experience with blacklighting let me know.  thanks.
