Re: Isn\'t this cute:
Also, I dont know that it would be wise to run them on a 14500 cell. I ran it for several minutes on a single CR123a and the light got pretty hot, I think another 1.2 volts might fry it.
I modified the heck out of mine. I ground the head down, then fitted a piece of PVC pipe to it and I'm going to put a copper or aluminum pipe inside to hold a single CR123a and a switch.
It sure as heck isnt much to look at, but.....
The head is made of some TOUGH aluminum, it took me half an hour to grind it down like that. The whole thing is covered in some epoxy that will be sanded down to give a good bonding surface for some black Krylon Fusion.
