For long battery life over light output, then I'd vote for the Fenix E01, too. Basically bulletproof light at a good price.

I personally EDC a Fenix E05 in my pocket. Won't last anywhere near as long as the E01, but it produces a very useful, bright, soft beam of light courtesy of its flood optic. I think it was recently discontinued, but can still be found for sale.
