Interesting, thanks for the informative post JohnN. It goes to show there's a headlamp out there for everyone. I've tried headlamps with 2-3 brightness settings, I prefer the simpler single brightness models. And I like the price of the Doug Ritter - I can buy two and have some change in my pocket for every Tikka I could buy. And I would rather go CR2032 or AA rather than CR123s. None of which is to diss other lamps, they work great for other folks. Face it though, I'm naturally cheap. One thing I like about the Petzl e+Lite - red light mode, I do wish I had that at times.
