The Nitecore NU43 headlamp brings power without breaking your back. Just a little over 4 ounces in weight, the NU43 is capable of a 1400 lumen max with a max beam throw of over 142 yards. Equipped with an upgraded unibody optical lens system, you get a combination dual LED spotlight to see in the distance, and a floodlight for close-up tasks and reading. Alternatively, switch to the auxiliary red light to protect your night vision or as a long-lasting signal light. The Nitecore NU43 is equipped with a built-in 3400mAh high-efficiency battery for extended runtimes of up to 165 hours on ultralow, and over 10 hours on high. The best news is that it can fully charge in under 2 hours via its hidden USB-C port. The highly efficient current circuit provides up to a full year of standby power making it a great candidate for emergency kits. Sharing the stage with the NU43 is a well-thought-out headband design. It is wider, more breathable, stretchy, and comfortable to wear. Nitecore NU43 is ready for the most vigorous exercises, and arduous tasks and wear for an extended time. The LED assembly is protected by an aluminum frame for increased impact resistance and the whole headlamp is rated IP68 waterproof. Additionally, built into the head of the LED array is a proximity sensor that automatically dims the light when approaching barriers, reducing harsh glare and reflection, and preventing overheating.
