The Black Diamond Onsight 375lm headlamp was developed after rigorous tests during night climbing on the limestone walls of Mexico and is our specially developed solution for climbers who need additional climbing time after sunset.
A climber's desire for simplicity and sturdiness has been built into every aspect of this lamp, from its one-button architecture to its fully waterproof IP67 construction.
The first thing you'll notice is the Onsight's dual-beam configuration, which offers the two main lighting modes climbers need most.
The main climbing mode has been optimized to illuminate the handles or the path directly in front of you with 300 lumens of evenly distributed light that does not dazzle when you are looking for the next climbing site or a small stand.
The secondary route finder mode adds a powerful, narrow, far-reaching beam of light and increases the maximum total output to 375 lumens so you can locate anchor points or search for trails in the distance.
The Onsight is dual fuel compatible and can be operated either with the rechargeable Li-ion battery BD 1800 or with three standard AAA batteries.
The front case is ultra-thin and has an extra hinge that allows you to get close to the wall and still see everything you need to see around you.
