Nitroz, yep, I'm curious just about purple. (Not a desperate desire for purple, but just a curiosity...) If you're interested in UV though, there are some options; take a look
here, for instance.
Size15's, wow, great pics! And that's a strange looking emitter.
Turbo_E, I did think of doing that. What is really cool is
this ; having seen that thing, if I started down that path, I wouldn't be happy stopping short of that...
Illum_the_nation, oh, I thought Luxeon Dental was the same thing as Royal Blue, until I looked at luxeonstar.com. I have a Royal Blue Lux-III FLuPic Q-III, which is neat ; and it produces a very deep blue color. Dental blue is even closer to UV, I gather? Oh, wait, I also have a Red/Orange light... Why didn't I think of trying them both before -- What happens if I shine them together at a wall.... <<where's the wifey's fancy digicam...>> Aha!!
A reference, to understand the scene; object presented for the sake of interest, and to give the digicam something to auto-focus on...
Royal Blue and Red/Orange, unfortunately they're much different reflectors. (Underexposed to avoid blooming)
What happens if I combine them??
Let me try a different approach... Here's blue-
Plus red-
Try to provide more opportunity for gradients-
I think my dodecahedron is going to melt...
