Lightweight Design for All-Day Comfort
The Right Light for Every Moment - Life isn’t one-size-fits-all, and neither is light. That’s why the NU27 offers three carefully calibrated beams:
- Warm light for misty mornings or rainy evenings, cutting through fog without glare.
- Neutral white for balanced, natural tones that feel effortless on the eyes.
- Cool white for crisp clarity, helping you focus and stay alert during nighttime tasks.
Hands-Free, Truly - The NU27 adapts to you. Use the comfortable headband for classic wear. Or take it off, and clip the headlamp to a cap, strap, or belt. The MOLLE-compatible clip makes it easy to use in whatever way works best for you. It’s not just hands-free. It’s seamless.
More Than a Headlamp - The included diffuser sack takes the NU27 beyond the ordinary. Slip the headlamp inside, and you have a soft, ambient lantern—perfect for relaxing at camp, reading in your tent, or adding a warm glow to any moment.
Built for the Unexpected - Rain? Dust? Drops? No problem. The NU27 is IP66-rated for tough conditions and built with durable PC materials. It’s designed to keep going, even when things get rough. And with up to 57 hours of battery life and USB-C fast charging, you can trust it to be ready whenever you are.
Details That Matter - The NU27 doesn’t just deliver light—it delivers control. A lockout mode prevents accidental activation when stored in your bag. The intuitive power indicator ensures you always know how much battery you have left. It’s thoughtful design, in every sense.

Brightness:bright and Good throw.. Quality:feels sturdy and super light Seller was fast to ship order, received in a day. Really appreciate it. Item even came with a small pouch to store the headlight.
All is good. Received product fast and prompt replies from seller. But yet to be put to the test. Will see how it performs out in the wild.
Very good and very fast shipping. Would recommend to friends and family not yet try.
Item was delivered in a day! It came with a stuff sack. I have not tested it outdoors yet, but works well.
Just got back from a camping trip with these. Awesome!
Suitability:Good Quality:Good Performance:Very bright and good The product came in good condition and is very bright!
Delivery is fast and well packaged as usual. Headlamp is very light and customisable strap with an elastic band. The light self has an inbuilt bracket that allows the body to cycle down in steps. This allows you to point the light at your preferred location be it straight ahead or at your feet all without bobbing your head.
2nd purchase . Love it for its light weight without being too intrusive for maintenance work . Strongly recommended
The light weight is a great plus point not only for sports but also a great substitute for prolonged work tasks. The variable light intensities helps control the work environment luminance.
Great light!! GREAT customer support with replacement reports available for purchase. Our Beagle chewed the backplate yesterday and I heard form customer service today with a link to purchase replacement part. The actual light was totally unscathed as was the beagle. Works as expected bright and I like the cord headband. If it can survive our beagle it can survive ANYTHING!! Recharges fast to boot!
These are my husband's favorite headlamps for everything from running to fishing. We love the rechargeable vs battery feature. Great variety of light settings, very versatile. My husband has had one for 2+ years and we have been very happy with its quality and functionality. We just bought 2 more for my son's, to use fishing, when the sun sets a bit before they can get back to the car. Get these, you won't be disappointed.
Suitability:Good Performance:Good Quality:Bright headlamp. Rechargeable. Perfect for hiking.
Have used this headlamp for 10+ sunrise hikes and some late night hikes so far. The dimmer white light setting is enough for myself when hiking, and bumping up to a brighter setting one or two other people can get by from my headlamp.The buttons take a little getting used to but work very well and once you learn what they do, are quick to use. Battery life is good but I would recharge it after hikes.Great value for the price since its an affordable unit. Very light as well
The perfect companion for a secondary light if ur heading to dark trail or even use as spare light if your main light is not working or forgotten to charge. It’s light, portable and comes with nice colours
Edc headlight, I don't feel it in my pocket, but it always with me.
Lightweight and most importantly easy to handle! It’s really comfortable I felt almost nothing ! Really amazing
My bar for headlamps is pretty high and this one is pretty good. It has a great light pattern, is lightweight and is comfortable to wear. The only option that it doesn’t have is memory for the last model used. This is a big deal especially when a light has so many options like the color temp and the intensity. I do like that there is a dedicated button for the red light, which you might use in the middle of the night to avoid blinding someone or messing up your night vision. I also really like the battery level test mode. It’s a set of 4 blue lights that come on temporarily when in use.
Honestly, this light is fantastic. It does all the things and then someI really like the way that it feels on the forehead and I like the gears in the back more than the nu20 or the nu25. They hold better and work betterThe nu27 crushes in all categories. It's also super super bright!Personally, for me it's too much light and I like the lightweight next to nothing convenience of the nu20 classic so that's the one I chose and that's the one I recommendBut if you need that bigger battery and more output this one is nearly perfect in every way

This is a must have for all the outdoor adventurers out there. This ultra lightweight outdoor headlamp is so compact that you can easily stash this in your pocket or backpack. It evens come in its own white drawstring carrying case for easy transport. This is perfect for camping, night biking or running, hiking and any other outdoor adventures especially since it’s so light and waterproof. There are different brightness levels from neutral white light, warm and then cool white light. It also has auxiliary red lights that can be used to signal for emergency help. It comes with its own black and yellow headband and it is very comfortable to wear around your head. The best feature is that it doesn’t use batteries and can be charged with the included USB charging cable. There are 4 blue light indicators letting you know its battery level. This headlamp is perfect in so many levels that I couldn’t ask for more. I highly recommend this.
Very bright and convenient Light weight
Really love the light. The really helps when out camping and the beam brightness and throw is great as well.
Apologies in advance for any typos, I accidentally blinded myself with 400 lumens of heavenly brightness before writing this review.Light, easy to use, feature packed. This headlamp has it all. Came in so clutch for camping and also when working on car, motorcycle, and even around the house. I bought two (home and shop) and maybe I'd get a third (moto trip bag).My wife makes fun of me for looking like a dork with a headlamp on. But she insists on keeping the lights off, so this was our compromise. Good time to mention the IP66 water resistance, works as advertised.Nitecore impresses with quality and feature set at a decent price.
Upgraded to this headlamp for the weight and color options. My other headlamp I still use but it's a tank (18650 batt). I've use NU27 on a 4 day backpack trip and it was so light I would forget I was wearing it sometimes. Battery life is great and the neutral color/ yellow is so much better for the eyes and color retention for certain items/tasks. The bad is there is no memory for the light/color options. Everytime it's powerd on it goes to neutral color in low then you will have to cycle through yellow then through white. (low-med-high) If I'm at camp and want a burst of white light i would have to hold to power on then dbl tap for turbo then press the mode button 2x to cycle through the color options to get white. Not an issue to me but just keep that in mind. Also have red lights which is a plus. Also I'm hoping the next gen will have a wider flood/flood option and memory. Other than all of that rambling, this is an amazing headlamp and my favorite right now.
Like the lightness of the headlamp, not forgetting the white that helps in finding inside the dark colored bag.
Nice design with 360lumens is enough for night fishing etc.
Useful as an edc, hands-off light. Used it when I was chasing lightning tube inside a dark room.
Lightweight, handy, practical!
Great headlamp overall. It is super lightweight, comfortable to wear, and looks sleek. The easy brightness adjustment and the ability to change the color temperature from cool to warm light is genuinely useful in different conditions. The build quality and materials are top-notch. Very satisfied with this purchase.
I bought this to go in my backpacking gear. It's super light, and very bright. The SOS function could be useful in case of a backcountry emergency.
It’s not bad. Not the most comfortable but good for the price.
I had another bigger branded headlamp with a single button, and I hated it. It was hard to always remember the sequence of presses, long presses, and number of presses to use the thing. This headlamp is simple to use all the features, like very simple. The charge easily lasts well beyond a camping weekend. Couldn't be happier.
Nice and bright, makes it’s easy to move around at night while camping or wherever you need light.
I’ve had this for nearly two years and use it regularly (camping, traveling, nighttime visits to the chicken coop). Still works as well as on day one. It only needs charging every 2-3 months unless I’m heading out camping.
This thing is awesome
Loved my last one, like this one too, would have been 5 stars if the charging port didn’t have the same end on both sides I thought one side would be usb, silly that it is not.
I have used Petzl and Black Diamond headlamps for decades. Looking to lighten my pack and this has not disappointed.
This headlamp did an incredible job during my recent AT walk. Light weight and simple to use, while being reliable. The headlamp's charge made it throughout the week long heat and humidity with no issues. Headlamp strap is simple but comfortable. I’ll be buying more of these for my Alaska excursions.
small and light. and the bungee rope strap is good for sweaty heads
Awesome head lamp this is my second one and first one lasted 2 years
