I freaking love this headlamp

- Reviewed in the United States on January 29, 2025Color: YellowVerified PurchaseLove, love, love this headlamp. Thinking of buying another one while they still sell them.
I bought it primarily for backpacking and camping but have found that I use it around the home and in the shop even more. It has become my go-to EDC (everyday carry) headlamp for sure.
Pros:
-USB C rechargeable w/ rubber cover to keep moisture out
-lightweight
-fantastic light output that's fully customizable
-simplistic 2 button design
-surprisingly comfortable stretchy cord fits on head well and is adjustable
-stretchy cord is reflective to easily find the headlamp at night or even off of moonlight in the tent
Cons:
-I wish battery life were a little longer. I would trade a bit more weight for a bit longer battery life. That being said, this headlamp is known for its stellar battery life. So don't fret about it too much.
- Reviewed in the United States on May 6, 2024Color: BlackVerified PurchaseThis LED headlamp has become an indispensable tool in my everyday carry arsenal, and for good reason. With its versatile functionality and compact design, it's proven itself to be a reliable companion in various situations, from outdoor adventures to everyday tasks.
One of the standout features of this headlamp is its multiple settings, which allow for customizable combinations of light output to suit different needs. Whether I'm navigating a dark trail or working on a project in low-light conditions, I can easily adjust the brightness and beam type to illuminate my surroundings with precision.
What's more, the headlamp packs away easily, making it a convenient addition to my EDC (everyday carry) kit. Its lightweight and compact form factor ensure that it takes up minimal space, yet it delivers maximum utility when needed. Whether stashed in a backpack or kept in my glove compartment, I always have it within reach for any unexpected situation that may arise.
One surprising use I've discovered for this headlamp is during my dog's ear cleaning routine. The hands-free illumination provided by the headlamp allows me to see clearly and navigate the delicate task with ease, ensuring that my furry friend receives the care they deserve without any hassle.
Overall, this LED headlamp has exceeded my expectations in terms of performance and convenience. Its multiple settings, compact design, and versatility make it a must-have for anyone looking to be prepared for whatever life throws their way. Whether you're an outdoor enthusiast, a DIY enthusiast, or a pet parent, this headlamp is sure to become an essential part of your toolkit.

This is a quality product that works great and is super lightweight and comfortable to wear for extended periods of time. It has all the light levels and colors you need for camping, hiking, working on the car. It packs up super small.
If you can afford it, get it. It will definitely last you and you won't be disappointed.
- Reviewed in the United States on January 28, 2025Color: YellowVerified PurchaseSuper light headlamp for backpackers. The battery life is very good and has lasted 3 day camping trips without charging. There is a meter on the top side which makes it for convenient way to check for charge. It did take a little getting used to all of the functions, but after the first night of messing around with all of the modes, you quickly get the hang of it. I mainly used the wide beam option for cooking and hanging around the campsite. The light is bright, but most importantly it is wide. The string straps adjust easily and work better than the traditional headband. Super value for the money.
- Reviewed in the United States on October 11, 2024Color: YellowVerified PurchaseThe strap is too fiddly and hard to keep from tangling and a little too small to boot. But it's easy to make a better version on the cheap and the light itself is pretty great. Nice battery life especially.
- Reviewed in the United States on October 19, 2024Color: BlackVerified PurchaseI use this item as a bicycle helmet head light. It is small enough to fit in a jersey pocket and gives me light where I'm looking (as a opposed to a bike mounted light which will probably give you light where you are already going). Very small, light, straps onto helmet quickly, fits in pocket, rechargeable, different modes of brightness (in traffic as opposed to on a dark bumpy trail). While not a super heavy duty solution, for getting home in the dark it works great. The helmet strapping/attachment is not great as I don't think it's actually designed for this, but it works fine for me.
I know these are popular for jigsaw puzzles and working in small spaces (tech workers), my use case is a bicycle head light.
- Reviewed in the United States on December 5, 2024Color: BlackVerified PurchasePerfect addition to my bug out bag! Lightweight, BRIGHT, dependable, comfortable. Like that its rechargeable! Plan to use on future ultra-light backpacking trips!
- Reviewed in the United States on January 3, 2025Color: YellowVerified PurchaseThe battery seems to last a long time. The modes are easy to operate and it get's plenty bright enough. I'm trying to only buy things that use USB-C these days, so that was important to me too.
I'm still up in the air about the "strap". I think I'll get used to it, but the two string elastics are different than a regular head band.
Top reviews from other countries
- Lord BergReviewed in Canada on December 31, 2024
5.0 out of 5 stars Lightweight and with plenty of functionality. What's not to like?
Color: BlackVerified PurchaseI've had this headlamp for about a month now. It's a solid little piece of gear - I think the battery claims listed on Nitecore's website might be a bit generous; 40 minutes seems to be the runtime at the highest setting.
It's also worth noting that due to overheating the headlamp will not remain at its 400 lumen mode - it'll stay there for about a minute before slowly reducing its output. It's still plenty bright - and realistically you'll be using either flood or spotlights interchangeably, as there's not much reason to have them both on at the same time.
As far as the red light goes - it's actually a bit too bright in my opinion. It's actually bright enough to hike by on a moonless night - not quickly, and I wouldn't trust it in difficult terrain, but on a flat trail you could absolutely hike using the red light.
Overall I'm quite satisfied with this headlamp. It's lightweight, functional (even has an SOS strobe built in, though I hope I'll never use that), and contrary to what many other folks claim has quiteintuitive controls for being a two-button device.
- V B.Reviewed in Canada on December 1, 2024
5.0 out of 5 stars Great power. Not comfortable on the head, but that's the tradeoff

- Jean-P T.Reviewed in Canada on August 26, 2024
5.0 out of 5 stars Does the job for camping
Color: YellowVerified PurchaseI've been using it for camping so far and I liked it, the "controls/buttons" might not be the most intuitive but it works : it's very lightweight and the "head/light" direction is adjustable so you can adjust it like you want, depending on what you do.
