Lightweight Headlamp

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.

USB-C Rechargeable

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.

Durable and Lightweight Design

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.

5 of 5 LOVE IT March 14, 2023
Reviewer: Joe Mayone from STAMFORD, CT United States  
A great addition to my "NITECORE collection." What's great about it? It's light and not uncomfortable to wear for extended periods. That in itself is impressive as this light carries a built-in 18650. As such, battery life is respectable. Brightness is also more than adequate. The detent for adjusting the light vertically is a big plus if you're constantly looking to illuminate the same field of vision. What could use a little nudge? The strap doesn't seem to stay tensioned for long. Not a big deal as I've learned how to quick-adjust it. But it shouldn't loosen so easily. And a wish. That you could turn it on and have it land on the last brightness. Neither are a deal-breaker. If I wear this one out I'd buy the same model again in a heartbeat. A very nice and light, bright headlamp. Five stars.

5 of 5 A bargain at twice the price. February 11, 2023
Reviewer: Mike from Reston, VA United States  
Excellent field of illumination, ample brightness and amazing runtime without a heavy battery pack. Simple, intuitive function and the remaining power gauge is awesome. If you find the mount hard just loosen the headband strap, it doesn't need to be tight.  This light compares favorably to competitor lights in the $100 - $200 range. At it's own price point it trounces the competition. After a session of use that would depleted my other headlights (from popular competitor brands) I checked the remaining power and the NU43 still read full!
