The Black Diamond Astro 300 Headlamp DualFuel is the perfect companion for outdoor enthusiasts who value simplicity, reliability, and versatility. Designed for those who want a dependable light without unnecessary bells and whistles, this headlamp delivers a maximum output of 300 lumens with intuitive one-lens, one-switch operation. Its DualFuel capability allows you to use either three AAA alkaline batteries or the rechargeable BD 1500 Li-ion battery (sold separately), providing flexibility for extended adventures away from power sources.
Whether you’re camping deep in the backcountry, training for early-morning runs, or navigating a race course at night, the Astro 300 keeps your path illuminated with confidence. Its lightweight design ensures comfortable wear for long periods, while IPX4 Stormproof construction withstands rain, sleet, and wet conditions from any angle. A digital lock mode safeguards against accidental activation during storage, and brightness memory ensures the headlamp powers on at your last used setting, avoiding sudden blinding light when you turn it on.
