Powerful and lightweight, the Petzl Swift RL Rechargeable Headlamp is the perfect lighting solution for serious nighttime adventures. This Petzl headlamp features Reactive Lighting technology that senses the ambient light and automatically adjusts brightness based on conditions. The headband is incredibly thin and easy to adjust, plus its split design is ideal for high-impact activities like running or skiing. Producing a maximum of 1,200 lumens that blasts through darkness for up to 168 meters, this headlamp switches seamlessly between Reactive Lighting or Standard Lighting modes, and a Boost mode activates 6 seconds of ultra-bright light. Integrated reflective cord ensures you remain visible to others, and the mixed beam is perfect for lighting up close or far away. A red-light option allows you to see without blinding those around you, while also offering a continuous or strobe mode. A single button controls on/off, lighting modes, brightness, and the locking function that prevents accidental activation. Built for outdoor adventures, the rechargeable battery maintains 90% of its burn time in temperatures as low as 23F. A 5-level charging indicator makes it easy to see the amount of battery life left.
