Meh I don't see the point of a 14500 light that is not dual fuel. If you want a light smaller than 18650, try 18350 or 16340 and anyway keep it small by not including a usb charger and maybe not a side switch. These manufacturers are too obsessed with high lumens because the unwashed buyers want that too. We (sniff) sophisticates have gotten past that by now, lol.
I'd change a few things about the Sofirn SP10 Pro if it were up to me, but it is basically the right idea if you want an AA-format light. The Manker E03 is another option, but I always want Anduril if I can get it.
