Trouble is finding a suitable filter though!
Smash a $2 75W incandescent black light and glue a shard over the die I guess?

Update!
Not sure if you guys already know but there are lots of feebayers selling 365nm 5mm LEDs. Seems to be different (and more expensive) than the old ones that did ~400nm. This guy (not the cheapest seller, BTW) even has a comparison picture.
I ordered a couple and will report back when they get here (probably a few months from now, don't wait for it..)
a "perfect" 365 nm UV light will look like a broken flashlight, with no visible light coming out
