I'm thinking of making a birthday present for my cousin. I have a 365nm 3-4W UV LED on a star, hooked up to a current regulator (that I bought long ago from unknown source), and 4-AA battery pack. It's just hacked together for testing, but my cousin, who is studying geology thought it was fantastic. (the UV makes certain minerals (rocks) fluoresce, which means something to him (to me, it's just kind of neat))
So what I'd like to do, is find a flashlight that's easy to disassemble, has a 20mm LED star on it and current regulator ALREADY, pop it apart, throw in the UV LED, and give it to him.
Any advice on where to find something like that? I have an old Pelican M3 LED flashlight that I've taken apart, put newer LED's (on star) in it from time to time, but it's well used, and I don't really want to give him that. Also, it takes CR-123 batteries, which are expensive to run. AA's would probably be best, but, I'm flexible, if it needs to be lithium batteries, I can get him some rechargeable ones & a charger.
I will probably use an LED like this (ebay link), the optics really don't matter. (this is what I hacked together that he thought was super cool)

If I'm in the wrong forum, or there's info already out there, feel free to kick this post wherever is needs to go. I didn't really see anything like I was looking for in the forum, but there's a lot of stuff here.
Thanks in advance,
