The opinion of Aventure Nordique
The Nao RL from Petzl is a headlamp that features the brand's Reactive Lighting technology. A sensor evaluates the ambient light and automatically adapts the lighting power to the user's needs. In Reactive Lighting mode, it delivers up to 1500 lumens for at least 2 hours, with a range of 200 meters. In medium power at 550 lumens, its autonomy increases to 5 hours minimum. It also has a Standard Lighting mode (fixed power, without using the sensor). Each mode has 3 levels of lighting intensity.
At the back of the battery pack is a red light, fixed or flashing.
