The Nitecore NU25 is a popular, ultralight, and versatile USB-rechargeable headlamp designed primarily for outdoor activities like hiking and running, but also excellent for everyday tasks. It features multiple light sources, typically including a main white light (up to 360 or 400 lumens depending on the version), an auxiliary high-CRI white light for accurate color rendition, and a red light for preserving night vision. It's known for its compact size, low weight, built-in Li-ion battery, and generally IP66 water resistance. There are different versions, including a newer "MCT" (Multi-Color Temperature) and "UL" (Ultralight) model with slightly improved specs and USB-C charging.
