Received the LEDs!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..)
