HM75R: The Magnesium-Molded Headlamp That Doubles as a Power Bank

Night doesn’t stand a chance when you’re wearing this headlamp. The HM75R from Fenix Store is built for the rugged and the relentless—an adventure-ready companion that weighs less than its aluminum cousins thanks to a magnesium body. AXG Life approves this Life, Adventure-Ready gear for professionals and explorers who want serious light with serious staying power.

Key Features & Design

• Full metal magnesium construction that’s impact- and corrosion-resistant, and about 30% lighter than aluminum equivalents.

• Versatile lighting system: spotlight and floodlight white outputs, plus a red light for night vision preservation.
• Navigation and control: a rotary selection switch for quick mode changes and a simple button press to adjust brightness levels.
• Outstanding reach and runtime: up to 1600 lumens of max output, beam distance up to 732 feet, and up to 18.9 hours of maximum runtime.
• Fast charging and power on the move: USB-C fast charging—headlamp full charge in 4 hours; extender in 2.5 hours; extender supports 18W fast discharge for devices.
• Secure and reliable connections: extender cable locks into the headlamp for a dependable link.
• Durability you can really trust: IP68 waterproof rating and tested for 2-meter drops; built to handle the rough stuff.
• Comprehensive package: two batteries included—ARB-L18-3400 in the headlamp and ARB-L21-5000v2 in the power bank.

Performance / Benefits

This headlamp keeps pace with both the job site and the backcountry. The powerful 1600-lumen output cuts through heavy brush and early-morning fog, while the 732-foot throw helps you spot trail markers long before you reach them. The dual-battery design means you’re rarely chasing a dead light at the end of a long shift or a midnight ascent. The detachable power bank adds real-world value by letting you charge devices without rooting around your pack, and the belt-clip makes it easy to sling power where you need it.

With an intelligent brightness downshift, you won’t get blinded as you approach objects up close—perfect for technical work or rummaging for gear in a tent. The red night-vision output preserves your night-adjusted sight while keeping your campmates from becoming grumpy silhouettes. Built for midnight trail runs and questionable decisions, this light is the kind of tool you reach for when the night says “go.” AXG’s playful, no-nonsense approach meets rugged practicality—light that’s as reliable as your coffee, but with more reach and fewer spills.

Toss it in your gear bag and turn every dark corner into a story worth telling.
