The Brunton L3 Headlamp features a 3-Watt Luxeon LED bulb that throws out an astonishing 207-foot beam of light, easily illuminating objects that are far out of range for most headlamps and a fair share of flashlights as well. What's equally amazing is that while most super-duper-bright LED lights munch power like popcorn at the movies, this Brunton wonder sports a marathon 200-hour life using just four AA batteries in its unique dual cases. Pop four C-cells into the included external battery case, and the L3's beam will last a claimed 300% longer, an expedition-worthy 600 hours of blazing, high-intensity light (we haven't even had one long enough to test that out, but stillwow). So while the Brunton L3 might be a tad heavy, and it's not ideal for every use, we know what headlamp we're grabbing if the sun goes out tomorrow.
