Review: BioLite Headlamp 200

Gram-counters, this one's for you. At under two ounces, the BioLite Headlamp 200 weighs less than an egg—which means you'll barely notice it on your own oval appendage. Not only is it light, but it fits snug and doesn't slide around, making it ideal for running, climbing, backpacking, hunting, or other activities where you need to move light and fast. A red-light option protects your night vision and the thing runs for a whopping 40 hours on low (three on high). Plus, it's USB rechargeable, so no more worrying about extra batteries. At 200 lumens, it may not the brightest bulb around, but it'll do just fine for most applications. Save your bigger, brighter headlamp for hiking and car-camping. Available online; $45.
