I was never going to post this light, but after giving away my remaining good stuff at Cambria, it was all I had left to offer for the Diesel Dave/disaster raffle.
About a year ago, I lucked into one of the Nichia 2W UV LEDs. I looked around in the junk pile and found some 3/4" 6061 tubing that I had knurled and had black, Type II anodized, and a Pelican reflector. (At least, I think that's what they're called.) I also had a loose BB500.
It was real Q&D- I bored the tube for 123 clearance and tapped both ends 11/16-24. I then turned and threaded the back of the reflector to fit the tube. (The reflector is the head.) I then knurled and threaded the tail plug/"switch."
Next came Arctic Alumina epoxy to mount the LED and hooking up the BadBoy. A machined phenolic tube served to space everything and keep it square. I tested it and it worked! Next came potting the sleeve with AA epoxy. It no longer worked. /ubbthreads/images/graemlins/frown.gif In retrospect, I probably had too much shoulder in the tube and disloged something. The fix ended up piggy-backing another BB500 onto the dead one. Fortunately the tube was still long enough as I had some really stoopid idea for a super-positive lockout that required extra tube length.
I could say that having no lense is to maximixe UV output. /ubbthreads/images/graemlins/icon15.gif The delrin lense cap does fit very snugly, and pulls a noticeable vacuum when you pry it off.
Not one of my better efforts, but it was intended as a personal tool for scorpion hunting. Not too long after building it, the group buy happened for the 6W's. /ubbthreads/images/graemlins/grin.gif
