The Nitecore NU43 redefines what a high-performance headlamp can be, combining exceptional brightness with ultralight convenience. Weighing just a little over 4 ounces, it holds the title of the world’s lightest 18650-powered headlamp while still delivering a powerful 1400-lumen output and a beam throw exceeding 142 yards. Its advanced unibody optical lens system houses dual white LEDs, providing a versatile mix of spotlight and floodlight for everything from long-range visibility to close-up tasks. Additionally, the integrated auxiliary red light preserves night vision and can serve as a reliable signaling tool in emergencies.
Built with efficiency in mind, the NU43 features a 3400mAh high-capacity rechargeable Li-ion battery that provides up to 165 hours of runtime on ultralow mode and more than 10 hours on high. Thanks to its hidden USB-C charging port and intelligent charging circuit, the NU43 can be fully recharged in under two hours. Its highly efficient power system allows the unit to remain in standby for up to a year, making it an ideal choice for emergency kits and long-term storage.
The NU43 also stands out for its thoughtful and rugged design. The headband is wide, stretchy, and highly breathable, ensuring maximum comfort even during extended use. The LED array is housed in an aluminum alloy frame for superior durability and is paired with a tough PC body to resist impacts up to two meters. Rated IP68, the NU43 is fully waterproof and dustproof, ready to withstand harsh environments. For added safety and convenience, the built-in proximity sensor automatically dims the light when approaching nearby objects, reducing glare and preventing overheating.
Engineered for versatility, the NU43 offers five brightness levels, three special modes, and intuitive one-handed operation through its dual-button interface. With clear battery indicators and robust build quality, it’s a reliable lighting solution for professionals, adventurers, and anyone needing high brightness in a compact, dependable form.
