    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.

    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. Light, bright, helps with my sight at night  star rating

      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

    2. Amazingly Light And Bright  star rating

      Posted by Mac Ciulla on 23rd Oct 2019

      I'll keep it simple. This headlamp is super lightweight yet comes with some powerful lighting!

      The red ight is great and having the UL head strap is fantastic!

    3. Does the Job But Not Quite As Well As I Had Expected  star rating

      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.

    4. I Think Literally The Best Headlamp  star rating

      Posted by Mark on 17th Sep 2019

      This thing is next level, super glad it was recommended to me!

    5. Very Comfortable  star rating

      Posted by Unknown on 16th Sep 2019

      Very Comfortable & light. Easy to switch out the bracket that came with the headlamp.

    6. Great little light  star rating

      Posted by Unknown on 8th Sep 2019

      I am using it to walk dark city street in early morning. When sun starts up, easy to put in my pocket. Lots of option for light. Haven't had a chance to use on trail yet. I like the rechargeable feature.

    7. Impossibly light, great features  star rating

      Posted by Mediocre Mountaineer on 6th Sep 2019

      This thing was SO light and conveniently small. Held a charge for my three day trip to the Pemi Loop, stashed easily in my hip belt pouch for quick access. The one lumen setting was clutch for reading in bed after a long day of hiking.

    8. Great!!!  star rating

      Posted by Scott on 2nd Sep 2019

      Nice and light. Exactly as promised. Love this light. Been looking for a full featured light that recharges and doesn't weight a ton and this fills the bill.

    9. Finally!!!  star rating

      Posted by CATHY on 24th Jun 2019

      Finally! - a headlamp that ticks all the boxes. Super ultralight; rechargeable; SIMPLE & LOGICAL method to change between lighting modes; red light function; lockable. I LOVE it!!!

    10. light and bright  star rating

      Posted by Samuel Marjamaa on 4th Jun 2019

      Easy to go through different settings, super bright at highest setting, good balance between brightness of redlights. Very happy with the purchase.
