User friendly upgrades and improvements over older models make this the new must-have if you want the latest in headlamp tech for your runs and activities.
TRIPLE OUTPUT HEADLAMP - Brighter, smaller, and longer running! The NU25 headlamp is an essential upgrade from the highly rated NU25 headlamp. New unibody optical lens system lets you switch freely between flood beam, spot beam, mixed beam and red beam illumination.
Ideal for close-up tasks and reading. Lastly, switch to the red LED and protect your night vision or use it as a long lasting signal light.
85 MIN USB-C FAST CHARGING - Built-in high capacity rechargeable battery gets you 4 hours runtime on on 200 lumens and 10 hours on 60 lumens. An integrated USB-C port fast charges to full in 85 mins. A power indicator tells you when it's time to charge while lockout mode prevents accidental activation.
LIGHT AND SAFE - The multithreaded headband cord has highly reflective bands for enhanced visibility, as well as glow-in-the-dark bands for visibility without ambient light.
The lightweight NU25 UL takes the center stage as Nitecore's lightest all-rounder headlamp for night running, outdoor adventures, or camping.
NU25 UL is the 2nd generation headlamp that fixes all the problems of the first version (NU25) and pushes it even further.
Smaller, brighter, more efficient, easier to use and longer running.
Since the release of the older NU25, Nitecore has been gathering over 3 years of feedback, learning from users on the ground on how to improve on the NU25.
The biggest improvement would be the new optical system that is far more efficient than the older reflector design. It has dedicated flood beam, spot beam, mixed beam and red beam.
2nd biggest change, the newly shaped dual button controls help you easily control the light without looking as the power and mode buttons now feel completely different.
The last big change is the new 4 stage power indicator that immediately shows you how much power is left.
A welcome addition compared to the hard-to-understand blinking models of the older versions.
If you've been looking for the latest and greatest headlamp for recreational / industrial use and still want it lightweight, this is your best match.
