Petzl has long been a pioneer in outdoor lighting, with its legacy dating back to the iconic Zoom release in 1981. And the Swift RL head torch follows in these footsteps. It weighs only 100 grams, and boosts 900 lumens of light output. That is truly impressive. The feature package is reduced to the essentials: You operate the torch with one single button, where you cycle through three different brightness levels. This button is small, yet glove-compatible and has a slide lock to prevent accidental activation when stowed away.And then there is the Reactive Lighting technology.  It operates on a simple yet brilliant principle: the lamp measures the distance from the observed object and adjusts brightness accordingly. So when you look at the map, it automatically lowers the brightness and then powers it up again when you look at the distance.Battery power is impressive: 2h burning on max, 50h burning on minimum, around 20h in standard setting with RL activated) Also, the battery almost doesn’t get affected by low temperatures. The headband is secures the lamp enough that you can jump and run with it.
