Alright guys, thanks to nitro for being a US distributor of Ahorton's aspheric lenses, I'm building two identical aspheric builds with Solarforce L2m's. One will be going on my AR-15, and the other will probably just sit around the house.
Now I have a few questions for the experts around here.
1.) What Cree LED should I go with? I like to order from US distributors, and ledsupply.com and illuminationsupply.com only have XP-E's (R3 and R4). I have some extra XR-E's sitting around, but I can't remember what they even came out of. It seems as though the XP-E would work great, but some say the XR-E is ideal.
2.) For my AR-15, I have a big pack of CR123A's sitting around and in my "bugout" bag. Using a 7135-based driver with one CR123 won't get me to max output, and 2 of them would burn up the 7135's (correct?). For a 17mm driver, outputting just over 1 amp, are there any other options? If not, I'll just run an RCR123 to get max output, then sacrifice output if I ever have to go to the CR123's (really, this won't happen).
I have a great idea for the heatsink, which will basically be a solid slug of copper or aluminum that fits inside the body and bottoms out where the body narrows down to 18mm. The 20mm LED star will be mounted on the front, and the driver on the back. Then two small screws or a pin will hold it in place, which means there won't be any spacers, and the twist of the head can be used to get the emitter in perfect focus. I'm sure this has been done before, but I'm excited to give it a shot.
Now, I just need to figure out where to get the slug of copper/aluminum, and if I should have someone like Chicago X machine one for me ;)
