What Our Gearhead® Experts Are Saying:"The Astro 300 is my ‘just-in-case’ light for every outing. It’s compact enough to tuck away, yet bright enough to handle surprise situations like navigating trails after sunset or sorting gear at camp. The Dual-Fuel option is a lifesaver for versatility on extended trips."For those moments when adventure takes a turn, the Black Diamond Astro 300 is our go-to headlamp. With 300 lumens of brightness and a compact, ergonomic design, it’s small enough to stash in a pocket but powerful enough to light the way when the sun dips unexpectedly.The Astro 300 offers Dual-Fuel compatibility, letting us choose between the rechargeable BD 1500 battery or standard AAA batteries for ultimate flexibility. Whether navigating a dark trail or handling camp chores, its dimming and strobe modes adapt to the moment. And with IPX4 stormproof construction, it holds strong against rain or sleet, ensuring reliability in any weather.
