Powerful and offers several lighting modes

The headlamp works perfectly and is easy to use. Several functions menu: soft lighting at full power flashes or night.
It also indicates when the battery is fully charged (green LED) or needs recharging (red LED).
It operates on battery power - no battery back - which can be annoying in nature without the possibility of connection. However, the lighting time is long and is perfect for a night "exploring", as it is announced up to 230 hours of lighting chosen.
It is light and its position is adjusted to about 45 °. Button to change the light mode is obvious, no need to fumble.
The lamp is inserted on an adjustable headband for a little over 2 cm wide, so not bothersome while being firm. Once set, it does not move.
It is an ideal equipment to be informed and keep your hands free, night hiking, running (especially when it is dark early in winter), the obstacle courses as Mud and De Bosses organized by Ose- association, and many others.

PS: The cable to recharge comes with, but it is a conventional cable usb / mini usb used by most smartphones. So if he remained in the box and you're already gone, this is not serious, he should phone and lamp can even load at the last minute in the car with a car charger.
