I see in Eagletacs literature that it says, "the GX25A3 is 14500 battery friendly." If it is putting out 738 lumens on three Enloops, how many lumens would it crank out on three 14500s? I wonder how it will compare to my Nitecore EA4? I would love to try four 14500s in my EA4 but I am scared as it would surely fry it. This makes the GX25A3 really interesting IMO
