The Petzl Swift RL rechargeable headlamp has a power of 900 lumens and ranks as the most powerful of the French brand's compact headlamps, designed for dynamic outdoor activities such as trail running, mountaineering or cycling. Swift RL is compact and lightweight with a weight of only 100 grams, equipped with a removable and washable band divided into two parts to offer you excellent grip and stability on the head. Featuring RL Reactive Lighting technology, the brightness is automatically adjusted using a special sensor, adapting to the ambient light and your needs. Among other things, thanks to this brightness sensor, the use of the battery is also optimized. If you set the front in Reactive Lighting mode (simply by holding down the start button) you will get a maximum output of 900 lumens that will allow you to see up to 150 meters for an autonomy of up to 30 hours and a guaranteed minimum of 2 hours. In standard mode, however, the power will be 300 lumens, for a distance of 55 meters and an autonomy of up to 40 hours. You can also set it to 100 lumens for maximum autonomy and a distance of 35 m. It also benefits from red illumination to ensure discretion and vision in darkness. The Swift RL is also equipped with a 2350 mAh lithium-ion rechargeable battery that recharges easily via a micro USB cable. How to use it is really easy to use, you have a single button that allows you access to all functions: On / Off, modes and levels of lighting and locking. Petzl Swift RL Pro rechargeable headlamp
