Why We Like The Onsight 375 Headlamp

For climbs that call for pre-dawn starts or hours post sunset, Black Diamond created the Onsight 375 Honnold Edition Headlamp. With a powerful 375-lumen design, the Onsight features two beam options, Climb Mode, which illuminates the trail or holds directly in front, or Route-Finder Mode, which adds a narrow, long-distance beam. Toggle between the Route-Finder and Climb mode with just a single tap, with a low-profile design that’s easy to wear with a climbing helmet.


  • A bright headlamp for climbing in the dark
  • 375-lumen design lights up the holds or access trail
  • Dual beam configuration designed with needs of climbers
  • Dual PowerTap tech toggles between modes
  • Low-profile housing seamlessly fits with a climbing helmet
  • Waterproof and dustproof design stands up to wear and tear

Simple and amazing

I have quite a collection of headlamps going these days but can't help buying better and brighter as they come out. The simplicity here intrigued me and I must say - it is simple and quick to switch between the 2 modes. I've been very pleased thus far.

Best for downright everything!

Exceptional headlamp. During recent evacuation from wildfire, I had major issue with my truck on way out of town. Of course it was the middle of the night and this was the only light I had with me. While looking for tools to troubleshoot the engine issue, I needed spotlight type lighting as well as a wider view shed of light. This headlamp did both. Provided exceptional light for walking down a dark dirt road to doing fine motor skill tasks such as picking up a tiny screw in the dirt. The headlamp is lightweight, very well balanced and dare I say, actually comfortable. Yes, because it was very comfortable to wear for over 4.5 hours at one time. I’d certainly recommend this headlamp to any outdoor enthusiast, from big wall climber to backpacker to fire fighter. It is now my “go to” headlamp!!

To support Alex's foundation

I do not climb yet. I bought this only to support Alex. I will use this when camping. I find it a little heavy and I was desappointed to find out the rechargeable lithium USB battery is not included. I read the description to fast, my bad!

Nice light

Nice bright light. Prolly have 4 hours so far on it and the batteries haven’t wavered at all. I bought the rechargeable one too so I’m not throwing trips away all the time.

A Great Headlamp

This is a great light. It can toggle from bright beam to broad view, and is light weight. I purchased the Ni-cad battery and charger also , for maximum versatility. Highly recommended.
