Flashlights have come a long, amazing way and you almost need an EE degree to understand it all. I have used Fenix primarily and not been disappointed but very much prefer American made. I need a one handed operation type (tail button to begin with but cannot use two hands to twist to go up and down luman load) that has a very long throw (think wilderness on a moonless night and need to see motion at least 400 yards and still fit in pocket) Too much to ask for? Doesn't (wouldn't be I guess)need a wide beam at all but up closer really light up a room. I noted Elzetta has Model C333 but it appears to require twisting to range it. Anyway, appreciate the help, somewhat complicated issues now with lights. This would be a more or less tactical application.
