Nitecore NU50 1400lm In-depth review, Pros and Cons

2 x unspecified White LED, 1 x unspecified Red LED
1400 lm output
3800 cd intensity
integrated 4000mAh Li-Ion battery

The Nitecore NU50 (NU50) released in 2023. It uses 2 x unspecified White LED, 1 x unspecified Red LED, TIR reflector and integrated 4000mAh Li-Ion battery. The powerful emitter in this headlamp provides up to 1400 lm output, 3800 cd intensity, and a beam distance of 123 m.

The NU50 is particularly useful in situations where you need to use both hands, such as camping, hiking, or working in low-light environments. It uses a TIR lens to form the beam pattern. This light has 5 + 2 modes of lighting. The mode memory of NU50 eliminates the need to cycle through different modes every time you turn on the flashlight, providing convenience and saving time. The USB charger port allows you to charge your flashlight using alternative power sources, making them even more suitable for outdoor adventures or emergency situations where access to electricity may be limited.

Nitecore NU50 (NU50) specifications

Rated 4/5 based on 287 user votes.

This headlamp is designed to emit light in the direction you are looking. This feature allows you to focus the beam precisely where you need it, providing better visibility and reducing the risk of accidents or mistakes.


Weight146 g
Length83.4 mm
Body diameter48.5 mm
Head diameter43.9 mm
Dimensions83.4 x 48.5 x 43.9 mm

The NU50 generally comfortable to hold for extended periods and easy to carry in pockets or bags. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue. The NU50 flashlight is available in black.


Emitter2 x unspecified White LED, 1 x unspecified Red LED
Color temperature6500 K
Switchdual electronic side

Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. A TIR lens works on the principle of total internal reflection. The TIR lens collimates the LED light into efficient, well-controlled light beams that maximize the usable lumens in the target area. The NU50 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.


Flux1400 lm
Intensity3800 cd
Throw123 m
CD/LM factor2.71

With 1400 lm, the NU50 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. With 3800 cd, the NU50 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.


Modes5 + 2 modes
Mode memoryyes
Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The NU50 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The NU50 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

The power source of the NU50 flashlight is integrated 4000mAh Li-Ion battery, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

This flashlight can charge the battery with an integrated charger, and it works with a USB power source. When the NU50 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The built-in thermal control automatically adjusts brightness output to prevent overheating.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the NU50 flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress. This flashlight is designed to withstand impacts of up to 2 m without sustaining significant damage, ensuring its durability and reliability even in challenging conditions.


Package contentsUSB Type-C cable

The performance of the Nitecore NU50 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
