The Petzl Nao+ is the latest iteration of Petzl innovative Nao headtorch which features their reactive lighting technology. The Nao Plus gives an impressive 750 lumens maximum output yet burn times are still impressively high when used in Reactive mode. The reactive lighting technology measures the amount of light being bounced back at the torch and adjusts the power and beam pattern accordingly, so that the relative light level remains the same. This allows you to have a useful level of light last a long time from a pretty small battery without having to continually adjust the power setting yourself.
The Nao+ is compatible with Petzl's MyPetzl Light app which connect to the torch via Bluetooth, this not only allows complete customisation of the preset modes but will also show information such as the remaining burn time for your Nao+. There are plenty if premade presets available for download to the app for multi activity, running etc or you can create your own personal ones from scratch. If apps are not really your thing then don't worry, the Nao+ is still perfectly useable without the app.
The Nao+ uses a custom Lithium battery which is charged via USB.
The headstrap is mostly cord with some elastic for a secure fit, which provides excellent support for the battery and the lamp on both your head and helmet. The cord is designed to be cinched up when in your pack so it doesn't come out in a tangled mess and there's an optional top strap, which is included.
Max Power mode prioritizes brightness. Max Autonomy mode prioritizes burn time.
