Developed after rigorous testing while night-climbing on the limestone walls of Mexico, the Onsight is our purpose-built solution for climbers seeking additional climb time after the sun has set. A climber’s desire for simplicity and robustness were built into every aspect of this light from the single button architecture to its fully submersible IP67 waterproof construction.
You’ll first notice the Onsight’s dual-beam configuration, which provides the two main lighting modes climbers need most. The main Climbing Mode was optimized for illuminating the holds or trail directly in front of you with 300 lumens of wide evenly dispersed light that doesn’t glare when you’re looking for the next crimper or small foothold.
The secondary Route-Finder Mode adds a powerful, narrow, long-distance beam and increases the total max output to 375 lumens allowing you to spot anchors or search for trails off in the distance. Black Diamond has added dual PowerTaptm technology to easily toggle between Climbing and Route-Finder Modes by touching either the right or left side of the front housing. Providing flexibility, the Onsight is Dual-Fuel compatible and can be powered with either our rechargeable BD 1800 Li-ion battery (sold separately) or with three standard AAA batteries (included). The front housing is ultra-thin and has extra articulation built into it allowing you to get close to the wall and still see everything you need to see around you.
Finally, at the highest waterproof rating of IP67, this light is fully submersible and dustproof, meaning it’s completely sealed and won’t be phased if you’re caught out in the rain.
