Description

Triple Output Headlamp

The NU25 is back lighter and more powerful than before with a dual beam spotlight and floodlight for a combined 400-lumen max that can reach out to 70 yards. Equipped with an upgraded unibody optical lens system switch freely between a primary spot LED, offering three brightness settings, to the flood LED for even wide illumination, ideal for close-up tasks and reading. Alternatively, switch to the dual red auxiliary LEDs and protect your night vision or long-lasting signal light. The NU25 is rated IP66 water resistant, features a bold new aerodynamic unibody design that efficiently dissipates heat, and looks stylish to boot.

USB-C Fast Charging

The NU25 has a built-in 650mAh rechargeable battery that can achieve a maximum runtime of 45 hours on its lowest setting. Now with an integrated USB-C port the NU25 fast charges to full in only one and a half hours. A power indicator tells you when it's time to charge while lockout mode prevents accidental activation. The intuitive dual-button interface puts the controls right at your fingertips so you have more time to enjoy the surroundings.

NU25 UL

The NU25 UL is the lightest headlamp, at only 1.59 ounces, optimized for the most dedicated outdoor enthusiast that takes carrying weight very seriously. The dual-band design evenly distributes the weight with a very simple cinching mechanism to control the tightness for user comfort. The multithreaded cord has highly reflective bands for enhanced visibility, as well as glow-in-the-dark bands for visibility without ambient light.

Best Headlamp Ever

I've tried a lot of headlamps, and I'm so glad to finally have found the Nitecore NU25. These are fantastic. My favorite feature is the straight to Red mode. It's hard to find a good red light, and this one actually works really well when you're trying to maintain a dark sky experience.

I also appreciate how the default mode is dim, and with each click the light gets brighter. Most headlamps are opposite.

And lastly, the bungee cords are genius. I love how lightweight everything is, and it's just a comfortable fit. I can have this thing on my head for hours without because I barely notice it's there.

10 out of 10....will recommend this headlamp to all my outdoor pals!

Great light!

This little light rules! It’s unbelievably lightweight and the strap is comfortable, though adjustment is kind of awkward and time consuming. I was worried that the many different light modes would make operation needlessly difficult and complicated, but that was not the case due to a perfectly intuitive button interface. The battery lasts forever and has a handy indicator. I only bought this light because it was lightweight and affordable, but it’s far and away the best headlamp I own. Could not recommend more. Super bright beam and reflective head strap. The low light setting is perfect for seeing around the house/campsite before dawn without straining tired eyes.

Great stuff

This headlamp was the perfect solution after my first nitecore snapped after years of hard use. I appreciate the updated charging port and bright color so I can easily find it in a dark bag

Solid little unit!

This is about as lightweight, fire and forget as a headlamp can get. Easy to use lamp and strap system. I like it a lot.

Doesn't work after 5 months

Used a few times and it worked great, but after 6 months it stopped charging and won't turn on. Nice and light, but if it breaks after 6 months of very light use, it's worthless

I honestly like the original NU 25 better but this one is still awesome

Great Headlamp

I ordered a used NU25 directly from Nitecore. It arrived a couple of days early. And just in time, too, because that night a wind storm came tearing through our neighborhood and knocked out our power the next morning. So the light got a 36 hour trial by darkness.

And it's a champ! It's light, comfortable, and easy to use. I've never used a shockcord type headband before, but it was great with a hat or without. It's so light weight I didn't mind having it on for long stretches while reading. There's a very short learning curve for the UI, but it's quite simple. All I really needed to know was double click on the right to go directly to the ultra-low 6 lumen setting, and then additional clicks take you through low, medium, and high. All I needed was the ultra-low because it's perfect for everything I need to do around the house and for reading. I could also have it tilted all the way down and my glasses didn't catch any glare. It's also easy to go directly to the red light with a single long press on the left button.

I used it for quite a while before I had the opportunity to recharge it. The battery was still nearly full.

I am very happy with this little light. It will be going into my main pack to go on every trip. And it's so light and small that I won't mind it coming along.

Exactly what I was looking for, and it delivers

I've been using a Streamlight bandit headlamp for years, and I'll give it credit where it's due-it's a featherweight light that has generally provided all the light I needed to get a job done. The headband has stretched to uselessness, however, in ~8 years that I've owned it, and I was looking for a possible brightness + runtime upgrade. I couldn't find any indication that Streamlight had updated the bandit in any significant way or produced an upgraded light that fit the same niche, so I grabbed the NU25 and have been pleasantly surprised with its performance. It's incredibly light and unobtrusive. The runtime is fantastic even on mid-bright settings, and the spot/flood options really make it useful in a wider variety of situations. I'd buy it again in a heartbeat if I lost the one I've got!

Great general use head lamp

Great lightweight package with the convenience of rechargeability. I use red light regularly and this is brighter than competitors lights.

Good little light

It's a nice little light, ultra light. The unusual stretchy headband took a little getting used to as did the multitude of settings for the light level- more complicated than- on low, medium, high, off. I used it as a utility light a couple of times and once on a two night trip on a boat. It works fine and is very bright. I have a feeling the battery charge isn't going to last as long as I'd hoped (used on lowest setting as much as possible) because the battery is half the capacity of my previous light from a well known manufacture from Europe that was recently lost. It also cost half what the other one did.

Amazing Battery Life!

My wife first bought this light and loved it so I bought one too. Light weight obviously but unbelievable battery life. We went on two weekend backpacking trips on one charge.

Light weight playing with a little bit, but haven’t really got to use it yet. Seems pretty cool.

Great, but limited weather resistance

I love, and I mean love this headlamp. It’s great in almost every way except water resistants. It’s my favorite headlamp I have ever owned, but my current one is dead. I am don’t a 550 mile hike and have experienced a lot of rain. The headlamp will easly get waterlogged and then stop working. As long as it’s fairly dry, it’s the best. I would not take it into the high country or in super critical situations until they come out with a model that is more weather resistant.

Looks pretty good so far

To be fair I just received this headlamp and haven’t had time to put it through the paces. The different lighting options seem good and intuitive to operate. For a very lightweight headlamp I prefer the design of the Petzl Bindi as it only has one small cord around the head. This one has two which really adds to the bulk.

Quick delivery and works as expected

Second headlamp I bought from NiteCore (1st was a NU25) and if either of these ever break down (doubtful), I'll be quick to purchase another. The battery life is second to none!

All I can say is WOW. This light is bright for being such a small packaging. I have a SF headlamp that cannot outshine this little light.

Love this Headlamp

We have been searching for a comfortable headlamp to use around the house, primarily for reading and not tripping over the cat at night in those areas that don't have lights. After doing some research, we decided on the NU25 UL. It's exactly what we wanted! From ordering to receiving, the process was fast and easy. And the headlamp itself is lightweight and comfortable. We both hightly recommend it!

Lightweight, minimalist, and comfortable

Even though the padding on this headlamp is minimal, it is surprisingly comfortable. Its light weight helps a lot. I can use this as my primary headlamp or keep it in my pack as an emergency backup. It's easy to use and seems to maintain a decent charge when kept on its lowest setting.
