The Black Diamond Spot Headlamp is a 300 lumen light for nighttime activities. Go for a run, hike, or just see your way around camp. The adjustable headband is soft against your forehead and at just 3.9 ounces (with batteries), you won't feel like a bobblehead. An IPX8 rating delivers waterproof Performance, so a rainy day or a dunk in the drink up to 3.3 feet for 30 minutes won't phase it.
