This offers an impressive maximum of 575 lumens and a 135m beam distance, which lasts around 6hr 30min. The Petzl NAO features reactive lighting technology, which adapts to the environment, and you can adjust your ‘perfect light profile’ via your computer. It’s comfortable to wear but I found the timing predictions for various profiles to be unreliable.  


An impressive head torch but quite complicated to use.
