BLACK DIAMOND Onsight 375 Headlamp

The BLACK DIAMOND Onsight 375 Headlamp is built for climbers who need both wide close-range illumination and a focused long-distance beam. Its DualBeam configuration gives you two tailored lighting options for route finding, climbing, approach, and belaying.

• DualBeam lighting: Climbing Mode provides 300 lumens of wide, evenly dispersed light to clearly illuminate holds and the trail directly in front of you. RouteFinder Mode adds a powerful narrow beam for long-distance visibility, increasing the total maximum output to 375 lumens.
• DualFuel compatibility: Use the rechargeable Lithium Ion BD 1800 battery for repeated charging cycles or rely on the included alkaline cells for instant power—flexibility for day trips or extended outings.
• Low-profile, articulated housing: The ultrathin front housing offers extra articulation for a comfortable fit and improved helmet compatibility when looking up on steep terrain.
• Purpose-driven design: Beam patterns and form factor are optimized to illuminate holds, routes, and approaches while minimizing bulk and snag points.

Compact and versatile, the Onsight 375 balances close-range flood light with a punchy long-range beam so you can move confidently in technical terrain after dark.
