I would like to help you out.
Since I don't have that light on hand, I would need the light and 2nd head to be sure it fits properly. Would you be able to do without them for a period of time?
An example of my work.

All true. I've tried several ways to make an LED module work for this light. The lack of space inside the head is killer.
I'm close to a solution (I hope).
I really love the SL20-X. I want to make them great again.
Chillinn, I got all of the following from engineeringtoolbox.com. Lots of good stuff there.

To the OP...
As simple as I can make it, the two main issues in the famous Al vs Cu debate are:
1. Copper is roughly 3x denser than Al, while it has 45% the specific heat capacity (roughly). Doing the math... 3 * .45 = 1.35 volumetric heat capacity (It's actually higher...
Thor Labs and Edmunds Optics both have very high quality lenses that will be < $50.00 for that size. Edmunds has the exact size you are looking for http://www.edmundoptics.com/optics/optical-lenses/aspheric-lenses/aspheric-condenser-lenses/43988. Thor Labs closest size is 30mm.
You need the...
Yeah, I will be putting a larger diameter on the end of the tail cap for sure.
I don't have any experience with high power incan lights. From the little I've read about them better soft start solutions are needed for the next level to come.
How about a triple XP-G2 driven by a 14500 at 6.3 amps? I may be making a few of these after my Damascus project is complete. Prototype is pictured. There will be a few changes such as the brass exposed pill will be made of copper instead. Probably a little machining embellishment here and...
Thanks! I will definitely do a thread for the Damascus build.
Here's the thread for the light shown above.
