Bright Headlamp with Spotlight, Floodlight and Red Light

The Nitecore NU40 headlamp is a versatile and convenient tool for outdoor activities like running, hiking, and camping. Weighing just over 4 ounces, this headlamp packs a punch with its maximum output of 1000 lumens and a beam throw of over 109 yards. The NU40 has a combined primary spotlight for long-distance vision, a floodlight for close-up tasks and reading, and an auxiliary red light to protect your night vision or use as a signal light. Its lightweight and waterproof design make it a reliable companion for all your outdoor adventures.

USB-C Rechargeable

The Nitecore NU40 headlamp is built to handle even the most strenuous activities, with a runtime of up to 120 hours on ultra-low mode and over 6 hours on high. It can be fully charged in just under 1.5 hours through its convenient fast-charging USB-C port. With standby power for up to a year, the NU40 is a great option for emergency kits. The proximity sensor is a unique feature that automatically dims the light when objects are near, reducing glare and preventing overheating. The NU40 also features a lock-out function and an ultra-low standby current, making it an ideal choice for emergency storage.

Durable and Lightweight Design

The Nitecore NU40 headlamp is paired with a well-designed headband, making it comfortable to wear for extended periods of time, even during intense activities. The headband is wider, more breathable, and stretchy, ensuring a comfortable fit for any head size. The LED assembly is protected by an aluminum frame, making it durable and resistant to impact. The entire headlamp is rated IP68 waterproof, making it suitable for even the toughest environments. The built-in proximity sensor, located in the head of the LED array, automatically dims the light when it comes into close proximity with obstacles, reducing glare, reflection, and preventing overheating.
