The best got better! Nitecore NU25 UL is an improved successor to the ultralight headlamp classic NU25, released in 2017. NU25 UL, as the name suggests, is a light weight headlamp with unrivaled performance and features for most hiking scenarios. It provides plenty of illumination in a simple, compact and most of all light package. You won’t even notice it’s in your backpack. Nitecore NU25 UL introduces several updates compared to its predecessor such as USB-C port, lighter headband as well as improved power and battery capacity. Despite the improved features and functionality the lamp weighs less than the previous model, weighing in at measly 45 grams. Nitecore NU25 UL is the best light weight headlamp for three season hiking at the moment and it also shines in trail running use.

Nitecore NU25 UL

In 2017 Nitecore introduced NU25 which quickly gained a cult following in the ultralight backpacking scene. Despite its legendary status NU25 had some shortcomings such as an overkill headband, micro-USB port, charging cable was in field of vision when charging the lamp while using it and of course there could always have been more lumens. Luckily in late 2022 Nitecore released NU25 UL which solves all these issues and offers some additional new features.

Instead of one main mode of light NU25 UL has two: a penetrating spot light and a broad flood light which both deliver 200 lumens of output each. Combined you get best of both worlds and 400 lumens of luminous flux. For camp chores the flood light mode can be set to 6 lumens which can last up to 45 hours on one charge. Additional auxiliary 10 lumen red light mode protects your ability to see in the dark and is also very useful around camp and especially in the tent at night.

Nitecore NU25 UL has switched from previous micro-USB to a new standardised USB-C port minimising the amount of cords and cables you need to carry with you. The port is also now placed on the side of the lamp instead of the bottom so the charging cable doesn’t interfere with your field of vision as it did with NU25 when recharging from a power bank while simultaneously using the lamp. Capacity of the lithium ion battery is increased to 650 mAh.

Headband has been thoroughly updated based on customer feedback. NU25 UL’s headband is minimal without compromising functionality, quite the contrary. It will remind some NU25 users of the replacement they have done with cords and a line lock on their NU25. The new headband in NU25 UL is reflective and glows in the dark.
