Nitecore NU25 UL LED Ultralight Rechargeable Headlamp Review

First Impressions of Nitecore NU25 UL LED Ultralight Rechargeable Headlamp

The Nitecore NU25 UL LED Ultralight Rechargeable Headlamp is the newest iteration of a headlamp already known for its impressive power-to-weight ratio. From Nitecore, this headlamp promises a blinding 400 lumens in a package that barely registers on the scales. With a dual beam, red light mode, and USB-C charging, this little light aims to be the ultimate companion for runners, hikers, and anyone needing hands-free illumination.

I’ve always struggled finding a headlamp that balances power and portability. Many ultralight options lack the necessary brightness, while brighter headlamps often feel bulky and cumbersome. The Nitecore NU25 UL seemed to offer a solution to this Goldilocks dilemma.

The unboxing experience was straightforward, the headlamp itself feeling surprisingly lightweight. The paracord strap, a departure from traditional headbands, immediately caught my eye with its minimalist design. The unibody construction felt solid, promising a degree of durability I wouldn’t expect from something so featherlight.

Compared to my older Petzl Tikka, which feels positively brick-like in comparison, and a bulkier Fenix HM61R, the NU25 UL is in a different weight class entirely. I chose the NU25 UL because I wanted something I could virtually forget I was wearing until I needed it. My initial excitement was high; this seemed like the perfect solution for early morning trail runs.

Real-World Testing: Putting Nitecore NU25 UL LED Ultralight Rechargeable Headlamp to the Test

First Use Experience

My first test was a pre-dawn trail run in the local foothills. The Nitecore NU25 UL’s 400 lumens lit up the path effectively, providing ample visibility for navigating rocky terrain. The dual-beam option proved particularly useful, allowing me to switch between a focused spotlight for distance and a wider floodlight for closer obstacles.

A light rain started about halfway through my run, but the IP66 water resistance of the NU25 UL gave me no cause for concern. The buttons remained easy to operate even with wet fingers, and the light output didn’t seem to diminish. I was pleasantly surprised by how comfortable the paracord strap was, distributing the weight evenly and preventing any pressure points.

Extended Use & Reliability

After several weeks of use, the Nitecore NU25 UL has become my go-to headlamp for nearly all my outdoor activities. It has accompanied me on multiple hikes, a weekend camping trip, and even a few late-night fishing expeditions. The durability has been impressive, with no visible signs of wear and tear despite being tossed into backpacks and subjected to minor impacts.

Maintenance has been a breeze, mostly requiring just a quick wipe down with a damp cloth after muddy runs. Compared to my older headlamps, which required frequent battery changes, the rechargeable NU25 UL is a significant upgrade. I’ve found the battery life to be consistent with Nitecore’s claims, easily lasting for multiple runs on a single charge.
