With reactive lighting technology, the brightness of the Petzl NAO 575L Headtorch adapts instantly and automatically to the environment. The headlamp thus provides maximal brightness (7 to 575 lumens), a longer burn time, along with greater usability and fewer manual interventions.
When in the reactive lighting mode, the brightness adapts instantly to what you need, thanks to the light sensor. The lamp offers adapted, comfortable lighting and helps keep the hands as free as possible while optimizing management of the energy source.
The Lithium-Ion rechargeable battery performs well at low temperatures and is easily rechargeable with the integrated USB connection. A battery charge indicator light tells you when it is running low and the battery can be replaced, if necessary, with two AAA/LR03 batteries at the cost of slightly reduced performance.
A constant lighting mode is also available, guaranteeing stable lighting that does not diminish during the entire chosen burn time. There are two lighting levels available, maximum power which is when brightness is prioritized and maximum autonomy which is when burn time is prioritized.
There is a lock function to avoid accidentally turning it on during transit or storage and the headlamp is stable on the head thanks to an adjustable headband with top strap for technical activities.
