The Nextorch C50 is a handheld LED flashlight from Nextorch, the Chinese maker of tactical and outdoor lighting. We could not find the current manufacturer page or a confirmed specification sheet for this exact model, so we cannot list its output, battery type or runtime here. Like other Nextorch torches it is built for everyday carry, outdoor use and work around the house, farm or vehicle. Please contact us before ordering if you need the exact lumen output, battery type or dimensions.
