Black Diamond Onsight 375 headlamp

Developed after rigorous testing during night climbing on the limestone walls of Mexico, the Onsight is our specially designed solution for climbers seeking additional climbing time after sunset. A climber's desire for simplicity and durability has been integrated into every aspect of this light, from the one-button operation to its fully submersible IP67 waterproof construction. At first glance, you'll notice the dual-beam configuration of the Onsight, which offers the two main lighting modes that climbers need most. The primary climbing mode has been optimized to illuminate the holds or the path directly in front of you with 300 lumens of wide, evenly distributed light that doesn’t blind you while searching for the next hold or foothold. The secondary route-finding mode adds a powerful, narrow, long-range beam and increases the maximum total output to 375 lumens, allowing you to spot anchors or search for routes in the distance. We have incorporated Dual PowerTap technology for easy switching between climbing and route-finding modes by simply touching either the right or left side of the front housing. The Onsight offers flexibility, is dual-operable, and can be powered either by our rechargeable BD 1800 lithium-ion battery or by three standard AAA batteries. The front housing is ultra-thin and features additional joints that allow you to get close to the wall while still seeing everything around you that you need to see. Finally, this light has the highest waterproof rating of IP67, is fully submersible, and dustproof, meaning it is completely sealed and unaffected if you get caught in the rain.
