Despite frequently depending on headlamps, for some reason comparing the attributes of various models goes beyond the limits of my gear geekery. I came across some pretty thorough testing of a broad range of headlamps on outdoorgearlab.com that I thought was well worth a look. *

I know this comparo is lacking some of the models we like around here, like the zebralights, but I still think its a pretty good resource to provide some empirical data on some popular models. Obviously, chime in if you've got something better than any of these…
*Headlamp geeks, please take it easy on me. I'm in know way endorsing outdoorgearlab's particular ratings or choice in headlamps. Just adding some data points.
