Petzl SWIFT RL (1,200 Lumen)

Adapts while walking. REACTIVE LIGHTING technology automatically changes the brightness based on your surroundings. This means you don't have to adjust it yourself as often when walking from open terrain into a dark forest.

Provides a clear view of technical terrain. The wide and focused beam helps you see both your direct foot placement and look ahead on fast descents. Especially when fatigued during long night trail runs, you will notice that you need to focus less on the controls.

Stays securely in place during vigorous movement. The thin, adjustable headband is designed for dynamic activities such as trail running, climbing, and skiing. This makes this light particularly interesting for long training sessions, ultras, and routes involving significant elevation changes and technical terrain.

Choose this one for long and demanding night runs. For short laps on illuminated trails, a simpler headlamp usually makes more sense.
