Great user interface, odd sizing - Nitecore MT10C CREE XM-L2 U2 EDC Tactical Flashlight w/Red Light

The controls are fantastic. It remembers the level it was set on last, so you can keep it on red always without having to search for it. You can always jump immediately to turbo mode or red light. The ability to press all 3 buttons and have it report battry voltage through light flashes is not something I'd seen before. The same mode works as a beacon every few seconds after reporting the battery voltage.

The downside is that it is large for pocket carry compared to other CR123 lights, and small and weak for putting in the normal places you'd mount a 1" tube light. I don't know where this light makes sense, because it isn't in my pocket, in my glovebox, or mounted.

I ran with Stremlight RCR123 and a Nightcore 18350, and couldn't tell much difference in light, but there was a very noticble difference in heat. (These were full batteries and I didn't run them to depletion, so as they discharge maybe the difference becomes noticible.)

I love having a light I can trust to come on red, that can flip to highest white light on demand. But given the strange in-beteen size it would be hard for me to recommend it.
