Petzl

Nao + Headlamp

As if the Nao + Headlamp's reactive lighting technology wasn't enough, Petzl went ahead and added Bluetooth compatibility to add a lot more convenience whether you're mountaineering, trekking, backpacking, or trail running. In case you haven't heard, reactive lighting technology automatically adjusts the headlamp's brightness based off the distance between you and whatever you're looking at, so the headlamp will dim if you're staring at a close rock, and if you're looking far away, the headlamp will turn on its high beams.

This technology is so advanced that you might not want it in certain applications, so you can switch from reactive to standard lighting manually or through Bluetooth. The Nao's Bluetooth allows you to connect the headlamp to your smartphone's MyPetzl Light app (downloaded for free) to adjust lighting levels, check battery levels, and even create your own profile with preset lighting levels; for example, you might desire more or less light when you're climbing versus when you're trail running, and you can adjust the headlamp accordingly at the press of a button before you take off.
