Nitecore® NU25 is a triple output USB rechargeable headlamp. The main LED has four brightness levels up to 360 lumens and a runtime of up to 160 hours on low plus two rescue modes. A red LED preserves night vision and an auxiliary high CRI white LED is great for reading. With our exclusive UL headband it’s light as a feather at just 1.17 oz (33.0 g). And recharge by simply plugging into a power bank. A thru hiker favorite.

NU25 has a micro-textured reflector providing 100˚ wide-angle flood illumination for outstanding night vision. The light tilts down up to 60˚ for reading or close-up work. The wide elastic headband is comfortable and highly adjustable to fit your head, hat, or helmet. Our optional UL headband reduces weight with full adjustability and functionality.


In addition to the main light, NU25 also has two auxiliary lights – red and white. The red LED helps preserve night vision and won’t blind your friends. Use low during star gazing or night photography, high for gear organizing or doing camp chores, or caution for a repeated short red flash.

The auxiliary white light uses a neutral white LED with high CRI ≥ 90 for more vivid, natural color and reduced eye strain. It’s great for short-range illumination, like reading a map. CRI (Color Rendering Index) is a measurement of how colors look under a light source as compared with sunlight. The index is measured from 0-100, with a perfect 100 indicating colors under the light source appear the same as they would under natural sunlight.


The headlamp has two buttons – Power and Red (R). For low light, press Power once. Within 3 sec, repeatedly press Power to cycle from low>medium>high>off. Hold down Red to immediately turn off or after 3 sec, press either button to turn off. Alternatively, for medium, press Power twice, and for high press Power three times. Hold down Red to turn off. To enter turbo mode, with the light turned on in any mode, hold down Power for 1 sec, and hold down Red to turn off.

You can also access two rescue modes, SOS and location beacon. SOS repeatedly flashes SOS in Morse code (. . . ––– . . .) The location beacon repeatedly flashes a single short flash. Hold down Power for 3 sec to enter SOS mode. Pressing Power within 3 sec again will change to beacon mode. After 3 sec, press either button to turn off.

For auxiliary white, hold down Power to turn on and hold down Red to turn off. For auxiliary red, press Red once for low, then within 3 sec, repeatedly press Red to cycle from low>high>caution>off. Hold down Red to turn off.

Press both buttons at the same time to lockout NU25 and prevent the light from turning on while in your pocket or pack. A red indicator blinks once to indicate lockout. Press both buttons again to reactivate the headlamp and enter low mode.

NU25 has a built-in, long-lasting 610 mAh Li-ion rechargeable battery that holds power equal to three AAA batteries yet is much more sustainable. An intelligent protective charging circuit and a Micro USB connection make it easy to recharge. Since you probably already carry a spare battery to charge your phone, there’s no need to worry about running out of power or replacing batteries, just plug into a power bank, wall charger, computer, or car (USB cable provided). The light maintains full functionality while charging.

To see how much battery power is left, with the light turned off, hold down the Red switch for 1 sec and release. The button will flash 3 times if you have more than 50% power, 2 times if you’re below 50%, and 1 time if you’re below 10%. Plug it in and an indicator light lets you know when the charge is complete. It takes approximately 2 hours to fully charge the battery. A rubber cover protects the USB port from dirt and moisture.

    Looking for this strap to make my headlamp ultra lite

    Posted by Smurfette on 16th Dec 2022

    Although I have not yet used this on trail, I sure wish I had this strap rather than the strap that came with my headlamp while on my thru hike. It was easy to add to my headlamp and fit on my head just fine. I got the bright color to be able to see the strapping easily.

    Excellent Ultra Light Headlamp for Long Distance Backpacking

    Posted by Melanie on 27th Nov 2022

    I used this headlamp for 5 months while thru-hiking the Appalachian Trail and it was great! I did have to replace the holder and UL headband after the hike, but that was easy and inexpensive. Highly recommend this product! One of my favorite pieces of gear on my hike!

    Can't beat it.

    Posted by Hiram on 26th Sep 2022

    The NU 25 is just the best, all the levels you need, red light at 2 levels, who does that. Quick recharge time, good run time super light weight. I did the first strap mod myself, I'm happy with the ressults. For me it's not about the weight it's the storage. It takes half the space in your hip belt pocket. Bought another mod with the light back for my second light. this is the only place I have seen just the backs for sale.

    Love this light

    Posted by Unknown on 4th Sep 2022

    Off the bat, I’ll say, I don’t have a ton of experience with this headlamp but so far I love it.. I didn’t realize how annoying my black diamond headlamps were until I experienced the ease of using this one. I really love the secondary (warmer) white light setting and the weight savings over my bd spots are significant. I did switch out the headstrap and I’m currently using one from an old bd spot 200. I ordered 2.4mm reflective shock cord and a second bracket and made my own minimalist strap but found it far too stiff for my taste. I tried again with 3mm non-reflective shock core from a local shop which was far stretchier and very comfortable. I will probably go back and forth between both straps depending if the situation. Lastly, I velcro’ed a third bracket to my bike helmet and it’s easy to pop it on when I ride at night. Love it. Great gear.

    This thing is the perfect headlamp. Three brightness settings on white and red light, super light, and fantastic battery life. Definitely get the shock-cord headband upgrade. It'd be more ideal to have USB-C charging port, but the battery life is so good it isn't a concern except for long, multi-day trips.

    14 hours on medium!

    Posted by Ken Olum on 1st Aug 2022

    It's been almost two years since I brought my NU25. I use it around the house and for backpacking. So I decided to see how it was doing. I charged it fully, turned it on medium (nominally 38 lumens), and left it running. Occasionally I turned it off and held the red button to see what it said about battery life. I didn't use any instrumentation. The manual says 8 hour runtime on this setting. After 6 hours it said it was down to its last 10%. After 14 hours in all, it was still running with something like the original brightness. In the 15th hour it got very dim, but still brighter than the 1-lumen low setting. This is much better than any test I've seen on the net. Probably not all units are as good as this, but for me it certainly delivered far more than promised.

    The Ideal Headlight

    Posted by Zach J on 20th Jul 2022

    I have been searching for the perfect headlamp for my backpacking trips and this is it. USB chargeable, several light modes, no accidental powering on while it is in my pack, lightweight, powerful. Perfect!!!!!!

    Wow! Super Light!!

    Posted by Monty M on 3rd Jul 2022

    I knew what the specs were but I was still amazed when I picked it up. I was also surprised how comfortable it is even with the cord strap system. You toggle through the brightness settings and it is nice that the first option is the lowest brightness. Many headlamps blind you in a tent while toggling to a dimmer setting. Medium is decent for hiking when trying to conserve the battery life. Low is not enough for hiking on a trail. You could get by in a pinch but it’s best for when you need a minimal amount of light.

    Lighter but not as comfortable.

    Posted by Michael Roark on 29th Jun 2022

    My Nitecore NU 25 is now lighter than my Bindi. However, replacing the wide band with the shock cord leaves the plastic pressed against my forehead. I’ll still use it.

    Light and very satisfying

    Posted by Unknown on 11th May 2022

    This thing is super nice. Well-made, I could have tried my hand at one myself, but it was very convenient to order from Lightsmith. The genius thing about the NU25 is, you can swap it very easily in its bracket. When the bracket with its shock cord strap arrived in the mail, it took me less than 30 seconds, and I halved the weight and dramatically decreased packable size of the lamp. This isn't an accessory to your EDC or ultralight setup that will make a key difference, but it's an affordable and fun upgrade which you won't regret! Now I want to buy one of these for all my friends who have the NU25!

    Light and comfortable

    Posted by John on 6th May 2022

    This thing just makes me smile. It is super light, which is why I purchased it, but I never realized how much I compromised my comfort with my brand band. This is so easy and quick to adjust that I adjust it for a different hat or helmet and it is easy to have dangling around my neck until I need it. A great purchase!

    2 headlamps are better than one!

    Posted by Bobo on 29th Apr 2022

    I bought this nitecore nu25 and fell in love with it, I was very impressed that litesmith puts the lightweight headband on. I don’t have the steady hand or the technology to pull off a procedure like that. Anyway, decided to buy a second one! Light up the night!

    Super bright

    Posted by Diane on 23rd Apr 2022

    This light is super bright and the elastic cord headband is better than the clunky one it comes with. Just don't accidentally put your light in the washing machine. It still worked afterward but it would sometimes malfunction and start going into the beacon mode even when it was turned off. I bought a replacement for it.

    Shock Cord Head Band Does What It Should!

    Posted by John H. on 30th Jan 2022

    My friends have bought the shock cord band and mount for the NU25 and it works great. I have one and I bought one for my runner daughter. Lightweight, stays put, the plastic band adapter fits the NU25 perfectly, etc. Can't go wrong with these.

    Literally the Perfect Headlamp

    Posted by Sunspot on 28th Sep 2021

    Used this on the PCT. This headlamp has a great variety of settings including red, and it's about as lightweight as you'll get from a headlamp. I made sure to charge it occasionally at night and it never ran out of power on me (although I did not do extensive night hiking, so I can't speak to its performance there - although I did use it once until about 2AM and it was still running well.) To me, the price of this was worth the labor that lightsmith does to change out the headband to the ultralight one, although if you wanted to save money you could totally do this on your own. The only issue I had was that the backing of the headlamp cracked, but honestly this was after several months of heavy use and I believe it happened because of where I stored it in my pack. Was able to replace just the backing & headband for like $10 and was more careful storing it after that and it's been great.

    Must Buy

    Posted by Steve on 24th Sep 2021

    Favorite Headlamp of All Time

    Posted by KTOD on 23rd Sep 2021

    This is the 3rd time I have purchased this headlamp (no problems with the first two, I just lost them). I have had so many different headlamps (some considerably more expensive than this one), and this is, by far, my favorite. It is compact, rechargeable, can be as bright as you could reasonably want, courteously dim, or red, and lasts a long time on a charge — what more could you want?

    Awesome lite light

    Thank you for adding the option of a cord headband with color options. I was going to have to change the original headband anyway but was glad to have it arrive ready to use. I’ve heard all about the light and knew I wanted it, it doesn’t disappoint. It was shipped promptly and used it immediately. It is the best!!

    finally found a great headlamp

    Posted by fdb on 9th Jun 2021

    I've been through so many and kept coming back to my old ptec headlamp. I have finally permanently replaced that with this nitecore NU25. It only weighs 1.1oz (as opposed to 3.3) and is better in every way. I love the 1 lumen option and the 190 lumens is plenty when you need more. Red light option is a must. Fantastic product. The skinny string style headband is shockingly comfortable.

    Posted by Benny on 4th May 2021

    What's is there to say. This thing is great. Only took it out one night sofar. But honestly the different options and the running time are where it's at. I had small yet powerful lights before and they don't even last a single night. This thing lasted the full night with me using it without worry.

    Initial review

    Posted by Unknown on 14th Apr 2021

    Haven't tested longevity of battery nor durability, but fit and finish are great. the customized shock cord works great -- super lighweight. I also have the Petzl Bindi. I'm not impressed with the Bindi battery life, so am excited to see if this NU25 performs longer. The shock cord on this one is skinnier than the Bindi, but totally sufficient. I do like the ability on the Bindi to rotate on the frame which I can't do on this one, but that's fine.

    Sometimes a little is a lot.

    Posted by Mojosaki on 11th Apr 2021

    This is a fantastic little innovation that improves the standard design. The standard Nitecore headband is fine but this makes it great. The adjustable cord makes it slightly lighter, more comfortable, and more adjustable. The smaller footprint also does not promote sweating whereas the standard one does on my head.

    Excellent Lightweight Headlamp

    Posted by Terry H. on 19th Mar 2021

    I’m a runner. I often run at night and need to see and be seen. I also get caught in the rain at times. This headlamp checks all the boxes for me. Bright, adjustable, long-lasting charge, very lightweight, multiple light modes, and waterproof. I couldn’t be happier.

    Great Heatlamp & Ultralight Headband

    Posted by Kyle Waggener on 8th Mar 2021

    I've been backpacking for over 30 years and have had a number of different lights and this is my favorite by far. It has a lot of different light modes, is very bright and you can turn it off with one push of a button without cycling through the other light modes. I really like the features like the battery charged light, the charge level indicator and the button lock. The reason that I bought the Nitecore NU25 from Litesmith was because of the ultralight headband that comes with it. Why have a headband the doubles the weight of the light? It is so light that you can't hardly tell that you're wearing it. Also, my wife & daughter have the same light and it's easy for us to keep our headlamps separate because we all got different colored headbands.

    Posted by Gray on 8th Mar 2021

    Purchased the UL headband and headlamp. Wasn't expecting it but it came with the original headband as well. Great! Got yellow and orange UL headbands (one for me and one for partner). Both are very neon/reflective and make it easy to find, which is nice bc the headlamp itself is black. When I ordered, I was a little worried about the comfort of the UL headband. BUT, I actually like the UL headband more than the original. I don't notice any difference in comfort, and it's easier to adjust than the standard strap. Weight is accurate to what's reported on litesmith. The charging cord is much longer than needed (unless you plan on hiking while charging it). I had a 0.5 ft. micro usb to usb-A charging cord lying around and it works fine, and is much lighter. Great features: - separate red/white buttons are great for not waking up your hiking buddy in the middle of the night - locking feature is awesome so you don't accidentally turn it on while it's in your pack. NOTE: charging a locked headlamp actually "unlocks" the lamp, meaning that the buttons will work again. Make sure you re-lock after charging if you're liable to turn it on accidentally while it's packed - you can check how much battery is left. Sweet! Brightness is great. Multiple levels of brightness ranging from 1 lumen up to 360 lumen. The second lowest brightness level is perfect for night hiking in my opinion. The brighter options are BRIGHT. the buttons are set up in a way that you don't have to cycle over all brightness levels when you want to power off. Couldn't recommend this more. So bright, so light, no frills but great features.

    This is like my 6th-7th headlamp in a decade. Some I lose and others I just don't like. This is a keeper. I can't think of anything to criticize. I love that the first on state is dimmest (unless you hold for turbo), so you don't blind yourself or others just to be able to see your shoes or whatever. I love that the dimmest is really dim and will last super long. I love that there is an alternate high-CRI flood for nice soft task lighting. Red is gravy. Super light and compact. Has lockout feature.

    A truly great product

    Posted by Tris Utschig on 12th Feb 2021

    I was able to put the Nu25 headlamp to use the day after it arrived (so glad it came on time exactly as expected) and it made my winter backpacking overnight immeasurably better than it would have been with any other light source I have used in the past. The gram weenie UL cord is so light it's hard to tell it's there and adjusts to fit over a headband or under a baseball style cap in moments. The bracket for angling the lamp works smoothly and is very stable. And, finally, the various lighting options were a huge benefit depending on wether I needed general lighting organizing my gear in the tent, directed light for reading, or bright light when I needed to go out looking for rocks to hold down my tent stakes from the heavy snow falling on my tent. I couldn't be more pleased.

    All I can say is wow, most user-friendly, affordable and lightest of the ultralight headlamp on the market. Not fumbling through one button for light modes in the dark and blinding myself/others is a lifesaver.

    This is my favorite headlamp I’ve ever owned. It’s so light I forget it’s ever in my pack. I now carry it on both day and overnight hikes as a safety backup. I use it almost every day this time of year because I pick herbs and spicy peppers from my garden when it’s dark to cook dinner with. In this at home scenario the battery last for 3-4 months before it needs to be charged again. I love that it’s USB rechargeable since I always carry a backup battery with me into the backcountry. My hobby is photography so the backup battery is inevitable. I love that if it runs out of juice it can be recharged in a few hours. I recently bought a second one for my girlfriend.

    The only option for this headlamp

    Posted by Dan on 19th Dec 2020

    The updated bracket and cord headband is the ONLY way to use this headlamp. The NU25 is a great headlamp and this update makes it that much better. I honestly forget I'm wearing it half the time once it's turned off and I'm still active. I don't typically review purchases online but for this I'm making an exception. Don't even hesitate, this is the one.

    Great light. Buy the UL headband also

    Posted by Shelley Chacon on 29th Nov 2020

    1. ditto what Randy S said on 11-20-2020 2. Buy the UL headband! Comfortable and totally worth it. (you could do yourself but not worth the effort for the cheap price charged!) 3. Very light weight given intensity. Best light out there in my opinion. 4. Also liked better than the Petzl Bindi (similar specs) as didn’t strain my eyes (watched a video where backpacker was reviewing both and the Petzl wouldn’t photograph as “dims” by turning off and on at high frequency and the Nitecore photographed fine so ACTUALLY dimmed. Not sure if this explains my eyestrain or not but like Nitecore better).

    Form and Function

    Posted by Randy S on 20th Nov 2020

    If you're on a Hiking trail and away from city lighting, you will probably be able to navigate at the lowest light setting, which is very low and offers very long battery usage time. The low Red setting is great if you have to find something in your tent without disturbing your partner from light. The high white setting lit up my backyard and will be good if you have car trouble and you need to see well, that setting is only 30 minutes though. Most everything you need to do around camp can be done at the mid setting. This light is small, and 1.1oz. and will sit in your jacket pocket without it feeling it is present. As with anything Lithium, do not charge it in the low 30’s or below, put it inside your jacket and let it warm up if charging off a power pack. This light is a good choice for a Thru Hike.

    excellent lightweight head strap

    Posted by L Land on 11th Nov 2020

    This nitecore headlamp is the current gold standard for lightweight hiking headlamps and the lightweight strap shaves even more grams. It is an excellent product.

    Big step up

    Posted by G on 14th Sep 2020

    This is a really great lamp - powerful white and red lights, each with three easy to use brightness levels. Unlike my other (black diamond) light, the red has enough power for walking around camp even when it's not fully dark yet. Also much easier to use than the controls on the BD light. I can't recommend this enough. If you're using an older light and want the latest tech, you won't be disappointed with this. And as a bonus it's super light weight.

    Lighter than air

    Posted by Unknown on 8th Sep 2020

    Weighing in at one ounce, this is a remarkably light headlamp. It's fully featured with differing levels of white or red light, and its USB rechargeable. The shock cord looks cool, saves more weight and you can choose your favorite color. It's the envy of my hiking buddies. Get one today!

    So light and so much light!

    Posted by Damon on 27th Aug 2020

    This is a great little light. I haven't tested the battery operating time but it's so light and easy to carry with me. I got the version with the strap replaced and I love it. It came with the bungee-style strap installed, the original strap included in the original packaging, and the charger. There is just something about receiving this already setup that made me so happy it was one less thing to worry about.

    Great headlamp, great service!

    Posted by Andreas on 18th Aug 2020

    A friend recommended some Litesmith products (e.g. this headlamp) a week before a backpacking trip. He is a fan of the store. I decided to order this headlamp and another item. After ordering I realized that the free shipping might cut it close. I called the number on the order confirmation and Peter immediately answered. He told me he would ship my items the next morning and it "should" arrive the day before I leave. With USPS's troubles I was a little worried, but hoped. Turns out I received the items even earlier, as Peter had upgraded my shipping for free to First Class. I'm impressed and will stay a customer of his. Oh, and the headlamp is great! Love the light and the orange neon string. I put the light on my head and did some things around the house and later searched for the light till I realized I was still wearing it. I had previously bought (and returned) a REI recommended rechargeable headlamp for about the same price and it didn't match the features nor lightweight of this headlamp. Very impressed!

    The perfect headlamp for lightweight distance hiking. Everything in the way of features that you need and nothing you don’t. Rechargeable, reasonably tough and compact. It is hard to see how this could be improved upon. Oh, get the lightweight headband, the other one is overkill for a lamp this small.

    Best thing I could find

    Posted by Jason McGrath on 30th Apr 2020

    I have a handful of headlamps, and I think this one beats all of them for your typical 3-season backpacking usage. The litesmith band is arguably more comfortable than the stock band, and is super easy to use. I've learned a lighter headlamp means you don't have to cinch it down as tight on your head. After fiddling with so many "one button" headlamps and having to relearn them on every trip, I am in love with this light's two button approach. Finally, it's rechargeable, and will even work while connected to a charger.

    Excellent lightweight headlamp

    Posted by Jim on 29th Apr 2020

    The Nightcore NU 25 is the best headlamp I have ever owned. It is so lightweight and is multifunctional. It operates with only two buttons and has multiple levels of both white and red lights. You can even use the two buttons to lock the light off so it does not turn on accidently while in your backpack. It only takes two hours to change the Li-ion battery.

    Great Headlamp

    Posted by Bradley K Felix on 14th Mar 2020

    I think the Litesmith converted SUL lamp is more comfortable than the regular wide strap. The NU25 is just the right size and brightness for backpacking. I like the swivel feature and the separate red button. Easy to use, easy to charge, comfortable; couldn't ask for more.

    Best UL Headlamp

    Posted by Rose Brown on 6th Mar 2020

    Exactly what I was looking for in an UL Headlamp. It has its own white and red light switch so it is easy to operate. What I love about this head lamp is that you can lock or turn off the headlamp so it won't turn on in your pack and run down the battery. It is easy to pack and the UL band stays on nicely. The headlamp and UL strap weighs at 1.12 ounces. I highly recommend this headlamp.

    Day hiker and camper

    Posted by Michael on 19th Jan 2020

    This NU25 is extremely light. It makes my older Black Diamond AAA headlamp, or my mini maglite that I used 20 years ago backpacking, feel like bricks in comparison. It also is extremely packable and takes up next to no space in my ditty sack. I love the way you can get an idea of how charged it is. The locking mechanism is simple and I haven't had an issue with it turning on in my pack. The red LED's really are worth it if you wake up before your partner or don't want to destroy your night vision. Ease of use is definitely a big +. I was initially worried about the UL headband being uncomfortable, but heard enough positive reviews to sway me into purchasing it from litesmith. I have not been disappointed by it at all. It's comfortable on the head, stays in place, and is so light I barely notice it. It's definitely a worthwhile upgrade over the standard strap that comes with the NU25.

    Fantastic Alternative Headband for the Nitecore NU 25

    Posted by Ray on 18th Jan 2020

    This should absolutely be a no brainer for anyone who purchases the Nitecore NU25 Headlamp. The strap that comes stock with headlamp is extreme overkill and simply isn't warranted for a 1 ounce headlamp. The stock Nitecore strap doubles the weight of the headlamp, and takes up valuable space in a backpack. With the Litesmith unit, I can take two headlamps for the same weight as a single one with the stock Nitecore strap. The Lightsmith comes with the same attachment as the Nitecore so you merely remove the Nitecore and attach this. Again, if you want to shave some weight and some space, do yourself a favor and get this strap...between the light and the strap, my scale shows 1.1 oz....just about as perfect as one can get for ultralight backpacking. Suggest getting one of the brighter colors make it easier to spot in the waning light of day

    Posted by Jared C on 16th Jan 2020

    Received the UL headband w/bracket and very impressed with the material! Was expecting the head band to feel more like a guy line, but this stuff is a super stretchy shock cord! Forms well around head and is very minimal which I like for both weight and packing purposes. Have not used in field yet but I am confident this will perform well. Really like the orange color and will be easy to find when I am fumbling around in the dark.

    Best Head Lamp at a Great Price

    Posted by Matthew Fulk on 27th Nov 2019

    I have had a lot of different types of head lamps over the years. The NU25 is by far the best head lamp I have owned. Great illumination and battery life. It's very comfortable to wear for long periods of time. Looking forward to a long term relationship with the NU25

    Light, bright, helps with my sight at night

    Posted by E Saburi on 6th Nov 2019

    I’m a flashlight/headlight geek (my brother in law is as well - so this is what we gift each other every Christmas). I have owned Petzls, Black Diamonds, Biolites -etc all of which are great products. But the Nitecore NU25 delivers great features in a super compact package that is light weight and reliable. If you’re counting grams/ounces - this is the light to get. And if you want to lighten it up further, Litesmith makes it easier with their cord modification. If you’re looking to get to that 10lbs base weight, this should be in your kit. *I promise this is an independent review - I am just that excited about this headlight. #flashlightgeek

    Does the Job But Not Quite As Well As I Had Expected

    Posted by Jeff Korhan on 16th Oct 2019

    My three criteria for this light were: 1. Light weight so I can carry it with me in a waist belt 2. Flexible for wearing on head, chest, or waist 3. Bright light The product is light and compact, especially with the cable for wearing it on your head, so that is how I've been using it. That checks #1 off. While it can be switched to a waist strap, you'll have to disassemble the cable, possibly forever. So, you basically have to choose one method or the other. Not sure if that checks #2 completely. The light is barely bright enough for me to safely run the streets of Chicago. There is ambient light around me so I need bright light to keep my path safe. There are lots of potholes and cracks in the sidewalk. This light gives me just enough to see them. I use the brightest setting, but it does not reach nearly as far ahead as my cheaper, but heavier $15 light. Lightness and portability were key factors, so I'm using it because the light is just enough to keep me safe if I'm careful. I didn't think I'd like the cable on my forehead but it's not a bother. Thus far I've used it for 4 or 5 miles without any discomfort. So, based on my use, If the light was 50% brighter I would call this a win and give it 5 stars. [Litesmith] Buy an extra mounting bracket for the wide strap then you can unclip the light from the UL strap and clip it on the wide strap for use around your chest or waist.

    I bought this item for camping. Have used it several times now and love it. I have it's little brother also the one with no red light. I love that this has a red light because I tend to blind everyone in camp while I am traipsing around looking for things. The white light is very bright and keeps a charge a long time. If left alone it stays charged much longer then I thought it would. I replaced my BIG headlight that I thought that I had to have. Your product showed me that I don't have to have big, heavy, or batteries. I highly recommend this product to anyone.

    Almost a perfect ultralight headlamp

    Posted by Nate L on 12th Apr 2019

    Great little light, especially if you are counting grams. Plenty bright to hike at night, and different brightness levels for when in camp. Having separate white and red buttons is great, no fumbling and doing the multi tap/hold dance trying to figure out a single button like some head lamps out there. Only 2 drawbacks are it charges off of a micro USB port when everything else I have now charges off of USB-C requiring carrying an extra cable. Secondly the rechargeable battery in it in not replaceable eventually making the whole headlamp a disposable item.

    This is the 4th Headlamp i have tried and its my favorite by far, ill only ever buy another if its a newer model. The UL band is perfect - light- comfy-secure. With the band its 1.1 oz on my scale. I'm trusting it to bring on the PCT this year and will be using it on the second brightest mode for night hiking- its the perfect brightness and lasts a long time on that setting. Also the 2 red light modes are set to the perfect brightness and mode 2 is the brightest red light ive had and i love it! This is the best headlamp ive ever used.

    Best Headlamp Yet

    Posted by J.R. on 12th Feb 2019

    I have been on a quest to find the best combo of functionality and lightweight. This NU25 is the best I have found to date. Although I can't speak yet to battery life, the red and white functions and brightness levels are easy to use and are suited for nearly all of the tasks for which I need a headlamp. The UL headband is really impressive. It is well made and works great with and without headgear.

    I already had an NU25 and bought UL headband. I bought the neon orange which makes it really easy to see in low light. The stock headband is .95 oz on my scale. The NU25 with the UL headband weighs 1.16 oz on my scale. So it's light. Plus it will be cooler when temps warm. I could have made my own but meh gathering supplies and I was ordering anyway... It seems to stay on my head as well as anything else. So it works, it's lightweight and easy to see, it didn't break the bank. Still lighter and less expensive than other brands. It's a winner.

    The best rechargeable lightweight lamp on the market

    Posted by Alex on 7th Sep 2018

    Yes, it is. And this UL headband from Litesmith makes it even better! Never used the standard strap. Tried the new Petzl Bindi, look at spec: Petzl Bindi: MAX AUTONOMY 5 lm 50 h 3 lm for 1h30 STANDARD 100 lm 23 m 3 h MAX POWER 200 lm 36 m 2 h 5 lm is nothing and 100/200 lm have the same miserable 2-3 hours of time. Pretty crap. NU 25 has 160 lm 30 min, 190 lm 5 h, 38lm 8 h and 1lm 160h. You should decide what is better for your purposes.

    just right

    Posted by Ty T Tibs on 4th Feb 2018

    was looking for something super light yet still strong for my thru hike. I got it with the lightweight headband and it weighs nothing. what i like about it is 1. super lightweight ( likely the lightest you will find) 2. Even though lightweight its just as strong as the heavier ones. 3. 4 brightness modes. 4. red light plus blink mode. 5. choosing different light modes is super easy. 6. adjustble degree of light direction. 7. rechargeable. For these reasons i give it a five star rating. What else do you need?
