I took the elk article down, because I was making fun of the author in the post. The author, I think, works for the park service, so I decided it wasn't a good idea to publicly call out the terrible grammar, spelling and the rest.
I like that Light , if I was in the market to buy one , I'd get it. But the geek in Me has me buying to raw parts to build one ( they are on order ) , as for 6 hour battery life, you should know the answear to that one. weight , Long term battery life , etc ,etc. also The batteies used in those battery Packs are just Basic 18650 LI-Ion cells which are used by Most lap tops and are easy to find , so I have a whole boat load of them.
