The Nebo CurvBeam 600 Flex is a low-profile headlamp built around a curved COB floodlight that throws a 180-degree band of light, reaching into your peripheral vision, plus a separate LED spotlight for distance. The flood gives 300 lumens, the spot 500 lumens and about 96 metres, and both together 600 lumens across six modes. The rear-mounted battery pack (BackBalance Fit) balances the weight so it does not bounce while you walk, run or hike, and the headband has a soft liner and universal sizing with 20 degrees of tilt. With Flex-Power it runs on its 1100mAh lithium polymer battery, charged by USB-C, or on disposable batteries as a backup. It is IPX4 water resistant and impact resistant. A USB-A to USB-C cable is included.
