Lanterna de cabeça Nitecore NU43 1400 lúmenes compacta leve

The NITECORE NU43 is a rechargeable headlamp with an integrated 18650 Li‑ion battery that balances low weight, high capacity and long runtime. Its dual-beam design allows spotlight and floodlight to operate together for a maximum output of 1,400 lumens and uses a unibody optical lens system with over 94% light transmission to provide uniform, soft illumination suitable for road and signage observation.

Advantages

Weighing 116 g (4.09 oz) and built from stamped aluminum alloy at the front with a specialized PC plastic rear housing, the NU43 combines strength, comfort and lightness. The built-in 3,400 mAh 18650 battery delivers up to 15 hours runtime on the 100-lumen MID level, supports USB-C reversible charging and can be used while charging. The headband has a concealed silicone strip to manage sweat and prevent slipping, and the near-center-of-gravity bracket reduces forehead pressure and stays stable during activity. The unit is IP68 rated, 2 m impact resistant, and includes multiple protection features such as sensor protection, transport guarantee and lockout mode.
