    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 to preserve night vision and an auxiliary high CRI white LED. 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.

    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.

    nu25-buttons.jpg

    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.

    1. Perfection!  star rating

      Posted by Art on 18th Mar 2019

      This is it! Amazing small, light and bright. The UL headband option is definitely worth it, very thoughtfully designed.

    2. The Best Headlamp - period.  star rating

      Posted by Nick on 17th Mar 2019

      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.

    3. Light and bright  star rating

      Posted by Robert on 10th Mar 2019

      Does what it needs to do, it's very light weight, and rechargeable. Great purchase.

    4. Everything I need, nothing I don't  star rating

      Posted by Kate Wheeler on 10th Mar 2019

      This is a great headlamp-- lightweight, bright enough to actually use at night, easy to operate red light mode, and rechargeable. I'm super satisfied with this purchase.

    5. Best Headlamp Yet  star rating

      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.

    6. your last headlamp is a child's toy  star rating

      Posted by rono on 7th Feb 2019

      this is the real deal. can't believe how light it is. the UL band is actually really comfortable.

    7. I like it  star rating

      Posted by Langly on 30th Dec 2018

      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.

    8. Great lamp  star rating

      Posted by melissacoy@charter.net on 19th Dec 2018

      I still need to trial in the field but very impressed with the light output, settings and weight. Very comfortable to wear. Look forward to having this piece of gear on the trail.

    9. Perfect Headlamp!  star rating

      Posted by Stephen on 2nd Dec 2018

      This is the perfect headlamp for hiking/backpacking! Puts out a great amount of light, love having the red light option for reading at night, and it's super lightweight (I got mine with the UL headband; even with the regular band it's still really light). It charges quickly, and I love having the lockout feature.

    10. Best decision  star rating

      Posted by Rudek on 30th Oct 2018

      Glad I bought this headlamp from Litesmith. Got it with the UL (shock cord), and it is perfect, great improvement from the original product. I made a mistake and ordered the wrong product so I immediately contacted customer service and they reply within minutes and fixed my mistake exceeding my expectations. If you are thinking about buying this headlamp, which I recommend, order it here.
