Greetings, I'm new to your forum. I'm trying to assemble a list of (mostly AA-powered) headlamps that are capable of even, full-flood lighting, as of 2011. Here's what I've got so far, care to add to the list (or take any away)?
[UPDATE: I've updated the information. Trying to post midrange (25-50) lumen and runtime specs when available.]
