Black Diamond Onsight Headlamp


Developed after rigorous testing while night-climbing on the limestone walls of Mexico, the Onsight is Black Diamond’s purpose-built solution for climbers seeking additional climb time after the sun has set.

  • Dual-beam configuration, providing the two main lighting modes climbers need most: Climbing Mode and Route-Finding Mode

  • Climbing Mode illuminates the holds or trail directly in front of you with 300 lumens of wide evenly dispersed light

  • Route-Finder Mode adds a powerful, narrow, long-distance beam and increases the total max output to 375 lumens

  • Dual PowerTap™ technology easily toggles between Climbing and Route-Finder Modes by touching both the right and left side of the front housing

  • Dual-Fuel: Maximum flexibility to utilize either the rechargeable Lithium Ion BD 1800 battery or Alkaline cells (Alkaline batteries included, Lithium Ion BD 1800 battery sold separately)

  • Ultra-thin front housing with extra articulation

  • Perforated elastic headband for breathability and lightweight performance

  • Six-setting 3 LED battery meter

  • Brightness Memory allows you to turn the light on and off at a chosen brightness without reverting back to full or mid-power

  • Digital lockout feature safeguards against accidental use when stored in a pack or pocket

  • IP67: Waterproof and dust proof—Unit is completely sealed and tested to operate up to 1 meter underwater for 30 minutes. Requires no maintenance after submersion.
