Thanks HarleyQuin, it looks like a confirmation for the MX900. Found this post by freeme on the A60 Review: Warsun X60 XM-L2 LED 5-Mode 26650 Flashlight and that looks exactly like the CT9T. He had the driver at 22.85mm. Probably could add the A10 also, from a pic by TomE Micro-review: The Warsun Collection MX-900 Find 6, X60, A9, A10, ET26, CT9T.... Initial Impression and some Pics!.
