The Petzl NAO headlamp features REACTIVE technology to automatically adapt light output on-the-run while also helping improve battery life. A sensor analyzes ambient light and proximity of objects in your path to adjust in real-time beam shape and brightness of 2 high output LED's from ultra-bright 355 max to 7 lumens. Customize settings on your computer to make NAO fit your needs for brightness and battery life. If you want, switch to constant mode for traditional headlamp function; Li-Ion battery recharges simply via standard USB.
