I own the dorcy cool blue (turtle light 1). and wondering about the PT impact or impact 2. on whether they can cast a farther beam than the cool blue? their sizes are all pretty small and i love the push button on my cool blue but wondering if the impact can throw a even farther beam. And is the impact running on a pr based led like the dorcy which you can swap in a incandescent quickly for some serious trail hiking light with a very very long throw.
