Headlamp Nitecore NU25 UL - 400 lm / Rechargeable

The Nitecore NU25 UL is a compact headlamp equipped with both a wide and narrow light pattern. Despite its compact size and weight of only 45 grams, the headlamp produces an impressive maximum luminous flux of 400 lumens with a range of 64 meters. Thanks to its high power in relation to its size and light weight, the NU25 UL is suitable for versatile use, from outdoor activities to jogging. NU25 UL offers a burning time from almost three hours to up to 45 hours. In this way, it can also be taken on long hikes, or for example longer runs. The headlamp also has a red light that preserves night vision, which can be used for example when reading maps, night photography or other similar activities.

The headband is made of light and elastic rubber band, a flexible and light material that adds practically no extra weight to the head. The band can be adjusted to fit any size, child or adult, using a convenient buckle and takes just seconds to adjust. With its durable material (polycarbonate) and enclosure class (IP66), the headlamp is protected against water and dust and is suitable for use all year round. The lamp's color temperature of 5500 Kelvin helps visibility in the dark, fog and rain.

The NU25 UL is powered by a built-in 650 mAh Li-ion battery, which can be conveniently charged via the lamp's USB-C port. The charging port is protected from water and dirt thanks to the silicone cover. The lamp's four battery indicator lights show the status of the battery charge. When four lights are on, the battery is 75-100%, three lights are 50-75%, two lights are 25-50%, and when one indicator is on, the battery is 0-25%. The battery status can be checked both during use and during charging. Five year (60 month) warranty!
