It's not often that we hear the words "throw" and "10-15 feet" in the same sentence. But the Sub Zero might have more uses than I ever thought possible (and probably some pretty impressive runtime as well.) I'd be very interested to hear just how well so low a level of light actually works on "dark nights while camping or hiking where a lot of light is not needed." After all, some of us have reached the age at which vision (or at least the ability to detect light) is already impaired to a degree, and might really need a bit more light. Quite honestly, for outdoor use I doubt that I'd go below a level 2 without either a LiIon or a 2XAAA Penlight to boost its output.
