Black Diamond Astro 300 Headlamp — AZUL

Black Diamond Astro 300 Headlamp

A compact, versatile headlamp built for hikers and climbers who want a reliable light small enough to carry just in case without sacrificing the output to handle unexpected situations. The Astro 300 delivers 300 lumens with Dual-Fuel compatibility so you're never stuck with a dead headlamp regardless of where you are or what batteries are available.

Why We Carry It
It's the headlamp we recommend for hikers who want a capable, lightweight backup light or a primary headlamp for casual use without the complexity of a fully featured technical headlamp.

Highlights

• Dual-Fuel compatibility — Runs on three standard AAA batteries included out of the box or the BD 1500 rechargeable Li-ion battery sold separately. A meaningful flexibility advantage for international travel, remote trips, and situations where recharging isn't possible but a hardware store is.
• 300 lumen max output with 55-meter beam distance — Enough light for trail navigation, unexpected rappels, and technical use in the dark. Three modes from 6 to 300 lumens cover the full range from all-night ambient camp use to maximum output on demanding terrain.
• Brightness Memory — Remembers your last brightness setting and returns to it on the next click without reverting to full power. A practical detail that eliminates the blinding full-bright flash every time you turn the headlamp on in the dark.
• 140-hour low mode runtime — Exceptional endurance on low for sustained camp use, emergency situations, and multi-day trips where battery conservation is a priority regardless of which battery type you're using.
• IPX4 stormproof housing — Withstands rain and sleet from any angle for reliable performance in the kind of weather that pushes hikes and climbs into unexpected nighttime territory.
• Patented digital lockout — Prevents accidental activation in a pack or pocket so the battery is full when you actually need it on a long approach or an unexpected bivy.
• Dimming and strobe modes — Customize the output for the situation from sustained trail running light to emergency signaling without carrying a separate device.
• 100-gram total weight — Light enough to justify carrying as a dedicated backup light or as a primary headlamp for hikers who want capable illumination without meaningful weight penalty.
