Black Diamond Onsight 375 Headlamp Torch - Aluminum

Whether you're hauling yourself up a limestone wall after dark or hunting for a trail anchor in the dead of night, the Onsight 375 Headlamp Aluminum is the climbing companion that keeps up without complaint. Born from rigorous testing on the night walls of Mexico, this headlamp was designed from the ground up with one clear purpose — giving climbers the light they need, exactly when they need it, without any fuss. With a single-button design, a dual-beam setup, and a fully submersible build, it's the kind of kit that earns its place on your harness every single time.

Key Benefits

• Dual-beam lighting modes: Climbing Mode delivers 300 lumens of wide, evenly dispersed light so you can spot holds and footholds without glare, while Route-Finder Mode kicks up a powerful, narrow long-distance beam reaching a maximum of 375 lumens to help you locate anchors and distant trails.
• Intuitive PowerTap control: Dual PowerTap technology lets you toggle between Climbing and Route-Finder Modes simply by touching the right or left side of the front housing — no fumbling around mid-climb.
• Dual-Fuel flexibility: Run it on the rechargeable BD 1800 Li-ion battery or standard AAA alkaline batteries (included), so you're never caught short whether you're on a quick after-work climb or a multi-day adventure.
• Fully waterproof and dustproof: Rated IP67, this headlamp is completely sealed and tested to operate up to one metre underwater for 30 minutes — rain, splashes, and dusty trails are no problem at all.
• Brightness Memory feature: Turn the light off and back on again at your chosen brightness level, so you're not blasting full beam when you just need a gentle glow.
• Smart digital lockout: The lockout function prevents accidental activation when the headlamp is packed away in your bag or pocket, saving battery life for when it actually matters.
• Ultra-thin and articulated housing: The slim front housing with extra articulation lets you get close to the wall while still maintaining a clear field of vision around you.
• Breathable headband design: The perforated elastic headband keeps things comfortable and ventilated during long, sweaty climbs — no hot spots, no fuss.
