Black Diamond Astro Ops 300 Headlamp Black, One Size

The Black Diamond Astro 300 headlamp runs on either a rechargeable battery or standard AAAs, so it never goes dark just because an outlet isn't nearby. At 300 lumens in a compact, low-profile body, it's small enough to ride in a jacket pocket without adding bulk. Dimming and strobe modes, plus a Brightness Memory setting that holds the last output level used, cover everything from sorting gear at camp to signaling in an emergency. What Our Gearhead(R) Experts Are Saying:"My rechargeable battery died three days into a trip with no outlet in sight, and three AAAs from a gas station got me through the rest of the week. That's the moment Dual-Fuel stopped being a spec and started being the reason I pack this over anything else."
