James Roddie tests the NEBO Curvebeam 600 Flex, an unusual but surprisingly proficient head torch.
The NEBO Curvebeam 600 Flex design is unusual. A flexible flood strip-light runs the width of your forehead, with a double spot lamp in the centre. The strip-light is made from flexible material with a rubber consistency, and this bends to wrap around your forehead.
James Roddie’s verdict
Overall, this is a surprisingly innovative head torch for a low price, and the flood light makes it well-suited for use around camp.- innovative design with flood and spot lamps

You can use either light independently, or both simultaneously, and adjust the brightness of both. Using both at the same time provides a very pleasing spread of light with a bright spot in the middle. This makes this head torch particularly useful in complex environments when your peripheral vision is important – for example when crossing a river or boulder field. There is no ability to tilt the angle of either light source. This will be a deal-breaker for some people. However, it is fixed at a 20° downwards angle which works well for most general use, and switching to the flood mode helps light your feet.
In general, it is simple and intuitive to operate. The two lamps have their own operation button, and you simply cycle through the brightness settings by single presses. However, the buttons are on the battery pack on the back of the torch. Whilst this is no problem most of the time, it quickly becomes irritating if you are wearing the head torch with a hood up. You either have to take your hood down to adjust brightness levels or wear the torch over the hood. Battery life is middle of the road. You get a maximum of 10 hours use from a charge, and that’s on the lowest setting of 30 lumens. Comfort is excellent, but the headband is not fully adjustable, and it will be simply too large for children.
Overall, this is a surprisingly innovative head torch for a low price, and the flood light makes it well-suited for use around camp.
