For such a tiny thing this flashlight can really throw light out, and the battery life is impressive as well. I used this on a thru hike of the Colorado trail followed by 4 years of all season use and abuse. Summer hiking and rock climbing at night, winter hiking/ski touring/ice climbing, I put this through the wringer. If you swap out the band for the ultralight litesmith shock cord the total weight becomes stupidly light at something like 33g. During this time I bought and broke 3 black diamond spot headlamps, nitecore construction and quality blows them out of the water. Now coming up on its 5th season of use the charging port is starting to break, it still works but it has to be kept in a very specific orientation to charge properly, the decision to buy another ... MoreFor such a tiny thing this flashlight can really throw light out, and the battery life is impressive as well.

I don’t know why I waited so long to purchase this headlamp as I am now able to easily walk my dog at night hands free without holding a flashlight. However, the big advantage is that this is the newer version. The headband is extremely comfortable and the adjustments to your size are flawless. Additionally the dual LED lights are sufficiently bright in all three settings with the combined spot and floodlights. The accessibility of the power indicator lights completely removes the guess work as to when you need to recharge the battery. The USB-C charging capability makes it a definite advantageous as well.

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 ... MoreI’m a flashlight junkie, When I found nitecore it was like “these guys get the obsession “ lights, batteries, gadgets, and hilarious videos.

I’ve used many headlights in my backpacking adventures and so far this is my favorite. Since I only recently purchased it this review is rather limited but I’m optimistic that this will be the “one”. Very bright when necessary and red light on high is bright enough to actually navigate around a campsite and do chores. I also appreciate the ability to lock it in the off position. I have a habit of flipping a battery over in my old headlights to avoid accidental activation which has happened several times. And speaking of batteries, I’m sick of them. I always carry a small battery pack so recharge on the trail is easy! The light weight is a huge plus as well. Definitely stoked so far and I’ll keep you posted.
This was my headlamp on a my 3000 mile CDT thru hike and was one of my favorite pieces of gear. This was my first rechargeable headlamp and I'm never going back to alkaline batteries. Super lightweight. No problems with fluid ingress. And kudos to your usability folks - So many headlamps have this nightmare of button patterns to switch modes, lock, etc. This was so easy and intuitive.Only ding: Wish this was USB-C. I would take a slightly larger headlamp in USB-C since I could leave a dedicated cable or dongle at home. Next iteration, right? Good job Nitecore
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 sectionsThis 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.
The LED headband strip is comfortable and stays in place well. It provides a light that is like walking under a street light. The back light adds safety by making you visible from behind. Love that they are recharging, they hold a charge well and can walk an hour with plenty of battery life left. I highly recommend these and just ordered a couple more-great price. Would be great as gifts too ❤️
I finally bought the NU25 after so many positive reviews from a variety of different sources. I understand the hype now. This headlamp is excellent. It's absolutely tiny, I barely notice it on my head. The UI is perfect, the mode spacing is great and the brightness is more than adequate. Especially given it's tiny size. The only two areas I see for improvement are upgrading the main LED to something with better CRI and a USB-C charging port.I bought this just weeks before the new NU25 UL release. At first I was bummed, but after seeing the mode spacing and UI, I am glad I got this version instead. The new, updated version seems like a step backward in many ways. Hopefully Nitecore reconsiders the UI for the new version.
Since I'm heading into bear country, I'm ditching my e+ lite. I want to be able to scan my camp out to 100' or more. I'd say great for backpacking and outstanding night running light, I'd up it for a lamp with 300-500 lumens and a robust battery for night hiking.Light output, throw, very nice. I think you could follow a trail on the "mid" setting and then hit "high" as needed - save the battery.Well built, seems solid, IMO the "high CRI" is more or less a reading light probably about 3,000K - maybe. I don't own a color spectrometer.1 lm on low is a NiteCore norm. I'd like to see 5 lm.I'd also like to see a USB-C instead of the "mini-USB" connector. Many Android phones and the battery pack I have now use USB-C. In time, you will see USB-C depreciating the ... MoreSince I'm heading into bear country, I'm ditching my e+ lite.
