5 of 5 Light and LONG battery 🔋 November 13, 2022
Reviewer: Wes Piatt  
I’m a flashlight junkie, When I found nitecore it was like “these guys get the obsession “ lights, batteries, gadgets, and hilarious videos. This is my 3rd light from them and it exceeded my expectations. Light weight: all my other headlamps use AAA batteries,
The nu25 is half the weight of my Black Diamond equivalent.
Battery life: I was out repairing equipment the other night and I didn’t realize I had both beams on high for over an hour. Convenient battery gauge showed full charge after running it like that. My other headlamps would have been at 2/3 easily.
Comfortable: details in the headband, high quality materials, very easy to adjust.
Beam spread: light choice makes choosing your beam spread easy and it throws plenty of light down. Critical for me is the option for the red light as well.
Con: my only wish would be the ability to dim it further on any setting.
Other than that it is my new go to headlamp, Thx Nitecore

5 of 5 Overnight success! November 8, 2022
Reviewer: Devin from Vermont  
It worked reliably from dusk to dawn. After 10 minutes of testing out the buttons and light modes (the included instructions are excellent) I was ready to hit the trails.
I found myself often using the floodlight on low (60 lumen) and it was sufficient for all but the most technical trail sections
This is my first Nitecore headlamp, so I can't speak to the previous model but I love the USB-C charging. I was pleasantly surprised with the hybrid headband - very comfortable, great grip, and quick adjustments are possible without taking it off.
