Nitecore's NU17 Ultralight USB Rechargeable headlamp is great little light-weight head torch with a decent brightness for its size.
Nitecore says:
The Nitecore NU17 headlamp has a maximum output of 130 lumens from the Cree XP-G2 S3 LED. It is powered by a built-in Li-ion battery which is rechargeable via a micro USB port on the top of the light, for quick, convenient charging.
The NU17 features multiple light sources which make it suitable for a range of applications, but thanks to its compact, lightweight design, it is the ideal running light. The headlamp has a primary white light, an auxiliary high CRI white light which provides accurate colour rendition on your surroundings and an auxiliary red light for enhanced night vision and signalling.
The Nitecore NU17 has a dual switch design which provides easy access to the three brightness levels, auxiliary modes and two special modes.
To ensure ultimate comfort, the included headband has a hidden silicone strip which diverts sweat to the sides of the head, preventing irritation in the eyes.
Nitecore's NU17 Ultralight USB Rechargeable Headlamp 130 Lumens is a useful little head torch. At its weight and size its no bother to always have it in your pack as an emergency. Just as useful to always have in the car at home for when you need it most. The red light feature which preserves your night vision and won't blind your companions is a real bonus on a torch of this size.
With convenient micro USB charging its easy to keep the lights on.
