1 meter = 39.37 inches = 3.28 feet

I feel the Petzl e+Lite serves as a fantastic backup headlight, and keep one in my GHB, my Bob, and my medical pack. The GHB and BoB both have larger Princeton Tec headlights in them as well, but it's pretty hard not to justify the redundancy provided by such a versatile headlight that weighs less than an ounce. Although the larger Princeton Tec headlights throw out more illumination, neither of them offer the red LED for maintenance of night vision.
