The Nitecore NU45 rechargeable headlamp is a versatile and high-performance lighting solution ideal for activities like working, camping, hiking, and night running. Powered by ultra-high efficiency (UHE) LEDs and a unibody optical lens system, it delivers a bright 1700 lumen beam that reaches distances up to 188 yards. Its TrueVision+ flood beam provides bright yet soft illumination, ensuring comfortable lighting over prolonged periods without causing glare or discomfort. Alongside the primary white light, the NU45 also features a high CRI auxiliary white light for accurate color rendering and an auxiliary red light designed to protect night vision and function as a long-lasting signal.
The NU45 offers three distinct lighting options to cover a wide range of needs. Users can cycle through four brightness levels on the primary white light by short-pressing the power button or activate turbo mode by double-pressing it. When the light is off, a double-press on the power button activates the reading light with two low-brightness modes, while a long press of the mode button switches to the red light, which has three modes: low, high, and slow flashing. Additional special modes include SOS and Beacon for emergencies. A built-in proximity sensor automatically adjusts brightness to prevent overheating and reduce blinding reflections, enhancing safety and comfort.
Weighing only 4.44 ounces, the NU45 is lightweight and comfortable for extended wear. Its 4000mAh rechargeable battery supports up to 86 hours of runtime on the lowest white-light setting and charges quickly via a USB-C port, reaching full power in approximately 1.5 hours. The headlamp includes a power indicator to alert users when charging is needed and features a lockout mode to prevent accidental activation. The NU45’s robust design includes an IP68 rating for waterproofing and dust resistance, along with impact resistance up to 2 meters, making it highly durable for outdoor use in varied environments.
As the latest model in Nitecore’s NU series, the NU45 represents significant advancements in performance, runtime, and comfort. It employs a multi-core LED setup with four UHE LEDs to maximize light efficiency while improving heat dissipation and reducing energy consumption, extending its usability during long outdoor adventures. The headlamp also benefits from an intelligent charging circuit and QC3.0 quick charge technology, delivering a peak charging power of 14W—40% higher than many competitors—and can reach 80% charge in just one hour.
The NU45 is designed for comfort with a widened 32mm lightweight headband and thickened foam padding to absorb shock, reduce pressure on the forehead, and repel sweat. Its modular construction allows quick detachment of the headlamp for swapping or mounting on alternate brackets. The headband itself can also be removed and used as a sweatband, adding versatility to the design. Made from durable PC material with an aluminum alloy front housing, the NU45 combines strength with lightweight convenience.
Equipped with two ergonomically shaped buttons for easy one-handed operation, the headlamp supports six brightness levels across three light sources and includes three special modes. Its ultra-low standby power consumption ensures readiness for up to a year when not in use. Four power indicators provide clear information on remaining battery life, while the stable output is maintained by a highly efficient constant current circuit without PWM flicker. Overall, the Nitecore NU45 is a reliable, feature-rich headlamp engineered for demanding outdoor conditions and everyday use.
