[ak47fans]

Here is Mzzlg's new burn bady M4X 16340 light. The light still not anodized. I got a raw parts from him and installed a light for testing only. Using an extended tube, it can use 18650 or 2 * 16340. It's shiny but it's aluminum only.
I replace the circuit from a M2X light. It is equipped with Q4-5B, Contant current cricuit LTC3454(800mA).

Add an extended tube to became a 18650 straight. Left:16340+extended kit Right:M2X(18650)

Here are their brother left to right: 16340, M1X(AA), M2X(18650)
