"uncle" kevinwrote a review of Petzl e+LITE Emergency Headlamp on March 13, 2009
this is the only light i used on my '08 appalachian trail thru-hike. it was perfect for the occasional late-push to reach camp and for all my nightly chores. i used it sparingly and never changed the battery in five months! i'll be using it for my pct thru-hike this summer.
