Ultralight, bright and extremely comfortable, the Nao RL shines when hiking as well as mountaineering and trail running thanks to its lightning-fast automatic brightness control.
If a low overall weight is important to you, the Petzl Nao RL is the best choice (for this, the Petzl also has one of the smallest batteries tested). For a short time, the lamp gives a good light, in continuous operation it is clearly less bright, but very economical.
