Innovative headlamp with smartphone connectivity.

As if Petzl's brightness-adjusting Reactive Lighting weren't innovative enough, the Reactik Plus Headlamp includes Bluetooth technology so you can personalize the headlamp via MyPetzl Light's app on your smartphone. Reactive Lighting automatically adjusts its brightness based off distance in order to provide a longer burn time, visual comfort, and minimal handling. Look from the trail to your skis or climbing harness, and you'll instantly notice the headlamp adjust its brightness from a powerful beam to a close-range light.

MyPetzl Light's application adapts the headlamp's performance to specific activities like trail running, mountaineering, trekking, or backpacking. You can also change the brightness, check the battery, and more with your smartphone. The Reactik Plus also features a rechargeable battery that can last for more than half a day, and to make sure you get the most out of the battery, Petzl included a lock function that prevents the headlamp from turning on when it's in your backpack. Petzl also added a partially-padded, adjustable, and washable headband, as if this headlamp weren't already completely convenient enough.
