The Nitecore NU25 is a compact, rechargeable head torch that is available in three different colours and offers a main white LED output as well as an auxiliary white light and a red light output.

The main white light provides a maximum output of 360 lumens from a Cree XP-G2 S3 LED and due to the micro textured reflector, it provides a central spot of light surrounded by wide angle flood lighting that provides a 100° angle of illumination for excellent peripheral vision. Additionally the head torch has a hinged bracket, that is hollowed to reduce weight, allowing the light to be tilted and adjusted within a 60° angle.

To the right of the main light there is a white auxiliary LED that has a high colour rendering index (CRI ≥ 90) and a colour temperature of 4500 K that provides an output of 20 lumens. The high CRI means the beam resembles that of morning sunlight, making colours appear more clearly to the human eye and also reducing eye strain, which makes this mode perfect for night reading.

There is also a red auxiliary LED that offers high, low and caution light outputs. Red light preserves your night vision and is good for wildlife observation, astronomy and night photography.

Four brightness levels as well as two special modes are available from the main LED and are operated with the left push button on the top of the head torch. A single press turns the light on in the low setting and then single press within 3 seconds to cycle through low, mid, high and off. After the light has been on for longer than 3 seconds the next press will turn it off.

Turbo is accessed by holding the power button down while the light is already on. The NU25 will stay in turbo for 30 seconds before dropping down to prevent overheating. The special modes are accessed from any state by holding the power button for 3 seconds to enter SOS and a single press within 3 seconds with toggle from SOS to location beacon.

The white auxiliary light is accessed by holding down the main power button while the light is off and pressing the main button after 3 seconds or holding the R button down will turn the white auxiliary off. The red light is operated with the R push button and a single press turns the red light on in the low setting and then single press within 3 seconds to cycle through red low, red high, red caution light and off. After the red light has been on for longer than 3 seconds the next press will turn it off.

The NU25 has an integrated 610 mAh lithium-ion battery, rated at 2.26 Wh and equivalent to three AAA batteries, that is charged via the micro-USB charging port. Reveal the port by lifting the dust cover on the bottom of the torch and then simply plug the included micro USB cable into the charging port and the other end into a computer/laptop or a suitable USB adaptor.

Featuring a unique design function, the NU25 remains fully functional while charging, so that you have access to light should you need it in an emergency. Alternatively it can be charged on the go with a powerbank, which is ideal for runners covering long distances.

A built in red power indicator between the buttons flashes to show the remaining battery power when you press and hold the R button for one second while the torch is off. Three flashes indicated more than 50% power, two flashes indicates below 50% power and one flash indicates below 10% power.

The NU25 has a lockout function to prevent accidental activation and is put into lockout mode by simultaneously holding both buttons down until the red LED indicator blinks once. To exit lockout mode hold both buttons down again.

Med: 38 lumens; 8 hours, 45 minutes run-time; 27 m beam range
Low: 1 lumens; 160 hours run-time; 3.8 m beam range
Auxiliary: 20 lumens; 6 hours, 15 minutes run-time; 5.5 m beam range
Red Low: 0.9 lumen; 68 hours run-time
Red High: 13 lumens; 7 hours, 45 minutes run-time; 4 m beam range
Red Flash: 13 lumens; 13 hours run-time
SOS: 360 lumens
Beacon: 360 lumens

Note: *Only stays in turbo mode for 30 seconds before dropping down to prevent overheat protection, therefore this run-time is based on a theoretical arithmetic. The turbo can be accessed again straight after it drops down, but if the NU25 becomes overheated it will stay in the lower output until the torch cools.

Tested to ANSI/NEMA FL1 standards with the integrated battery fully charged in laboratory conditions. End user results may vary due to individual usage habits and environmental conditions.

I have found this to be a great lightweight headtorch, plenty of lighting options and a pretty good user interface. Amazingly small for it's light output and has a very comfortable headband.
