Nitecore NU25 Head Torch - 360 Lumen USB Rechargeable Headlamp – Lightweight Waterproof Head Torch with Red Light

Product Information

The NITECORE NU25 Dual Beam USB-C Rechargeable Headlamp is available with 3 light sources. Utilizing dual primary lights — Spotlight and Floodlight, it can produce a max output of 400 lumens with a light transmission of over 94%. It is all weather applicable as IP66 rated

Two smaller red LEDs sit in the centre and provide constant red or red flashing outputs, which preserves your night vision and is good for wildlife observation, astronomy and night photography.Sadly there is no mention of CRI nor much info on the optics. The flood is claimed to be 100 degrees but I couldn’t find info on the spot beam. However, visually one can clearly see a difference between the two beam profiles. The NU25 UL is a really compact and lightweight headtorch. For me this is ideal, as the times I want a headtorch are when I’m crawling under the car or maybe when in the loft (attic) going up and down a ladder. Having something that you hardly notice on your head, but that offers a nice beam and tint is very handy in my book. As for the in-built battery, I have no problems with this at all and I suspect it is the future of lights like this. The Nitecore NU25 UL has a large and comprehensive set of modes and options. This is a dual beam headlamp, which means it has 2 x LEDs. But it is more than just two outputs. One LED is coupled to a floody TIR optic while the other TIR optic is designed more for throw. We are delighted to announce that Fuzhao Xiang and Rongrong Chen join the NITECORE family as our new NITECORE ambassadors. Both of them are professional trail runners as they are always full of expectation on the trail races, and keep striving for better achievement. In the future, we will help and support them with our excellent products, taking them to the next level. The popular Nitecore NU25 rechargeable head torch has been updated to the New version, now offering a spot LED and a flood LED that can be used individually or combined, as well as still keeping the secondary red light output as before.

In practice however, both buttons seem to be able to turn the light on and off and both can change modes. But each button does different things from the other. This means you need to have a very good memory on which button to press at which time. I’ve found I have had to refer to the instruction manual many times and then still end up forgetting. This means each time you use the NU25UL it does feel a bit like trial and error. There are no metal parts on the Nitecore NU25 UL, this is deliberate to keep the weight down. It appears to be mostly made of some kind of ABS plastic. It feels both durable and high quality. I have no concerns over the build quality, fit and finish appears to be superb. We are delighted to announce that Scotty Hawker joins the NITECORE family as a new NITECORE ambassador in 2022. In the future, we will help and support him with our excellent products, taking him to the next level. On July 7, 2023, NITECORE has officially become the designated headlamp sponsor for the Hong Kong TransLantau™ by UTMB®. As part of the partnership, NITECORE will bring its cutting-edge innovations to support the event and to help runners perform at their best.The headband itself is very minimal, using a double elastic cord. This does keep the weight down, although I did find that on my hair (which is fairly long), that it did want to slip a bit. My Opple light meter confirms the dual white LEDs have a CCT (k) value of 5409 and an Ra of 70.2, while the red LEDs have a 5002 CCT(k).

ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries. Peak beam intensity and beam distance measurements Mode The battery is 650mAh in-built Li-ion, broadly equivalent to the power/runtime of a 14500 Li-ion cell. But being in-built the battery can be of a different shape, allowing the NU25 UL to be much smaller than it would be if it had used a 14500. The world’s largest Outdoor Hunting Products Exhibition – IWA Outdoor Classics 2023 is held in Nuremberg from March 2nd to 5th. As one of the world’s top tactical, hunting, outdoor and personal protective equipment trade fair, IWA shows the most dazzling and coolest tactical equipment and the world’s top equipment brands. At the same time, IWA is also a “paradise” for all kinds of fans of hunting and outdoor sports. On February 10th-12th, 2023, ISPO Beijing is held at the China National Convention Center in Beijing. It has been 4 years since the last ISPO Beijing and has also been actively supported by a large number of outdoor enthusiasts. Note: most of the following review was copied from the Nitecore NU25 review, which is the same headlamp except for the head strap.

As there are so many different LED and output combos on the Nitecore NU25 UL, I decided to simply measure the highest output using the combo beam. If I have any complaints with the NU25 UL it is the User Interface. You have two buttons to interact with, both located on top of the unit. One says Power, the other Mode. Which in principle sounds completely rational. The new NU25 has an integrated 650 mAh lithium-ion battery that is charged via the USB-C charging port on the side of the torch. Reveal the port by lifting the dust cover and then simply plug the included USB-C cable into the charging port and the other end into a suitable USB power source. The charging indicators on the top will flash in turn before becoming solid, and once all four indicators are solid after approx. 1 hour, 25 minutes the charging will be complete.

You can either have one LED or the other in use or both together. In all modes you also have differing output modes. This makes the headlight very versatile and gives the user easy ways to extend runtimes. Although maybe at the sacrifice of introducing a fairly complex and confusing user interface. 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 cannot guarantee my lightbox produces the same lumen numbers as the integrated spheres used at a commercial level. However the lumens I recorded are close enough for me to believe this light puts out the claimed figures. Lumen measurements Mode
