The headlamp for challenges - the Nao+ by Petzl! This headlamp comes with an external rechargeable battery to distribute the weight better on your head and to provide more comfort in combination with a two-part, adjustable headband. The rechargeable battery has a capacity of 2600 mAh and is therefore very powerful. Using a USB cable it can be recharged in 6 hours and can be replaced of course, so that you always have a warm rechargeable battery on you when it cold for example. The LEDs of the Nao+ allow for a wide variety of light beams depending on whether you need to see in the distance or at close range. In Power mode it uses up to 750 Lumen and is visible for 140 m! Thus, you can illuminate each and every corner of rough and unpredictable terrains perfectly! You not only have four brightness levels (Max Autonomy, Max Power, Distant view, Close range) but also have the choice between Constant Lightning and Reactive Lightning Technology. Pick the first one, if you want a constantly bright light cone which you can control yourself. If you choose the Reactive Lightning Technology theres a special brightness sensor adjusting the intensity of the light automatically - thus, you dont have to operate the lamp with your hands and can fully concentrate on the path and your hand movements. Another nice feature is that the Nao+ is compatible with the MyPetzl Light Smartphone app, which is possible due to a Bluetooth interface. That way, you can create several lighting profiles, see the battery status in real-time, adjust the duration of the light and much more. In other words, the Petzl Nao+ is a headlamp for all those who want to concentrate on the essential things on changing, challenging terrains!
