Product Review

The NITECORE NU25 utilizes three light sources (white, red and high CRI) to create a versatile and lightweight headlamp you'll find endless uses for. A powerful CREE XP-G2 S3 LED capable of 360 lumen and a 88 yard throw serves as the main output and is useful for outdoor activities like running, cycling, hiking and camping. There's also an auxiliary red LED that helps preserve night vision for nighttime photography, map reading and stargazing while an auxiliary high CRI LED produces a warm, floody beam ideal for up close reading and detail work. Dual switches located on the top of the unit provide easy access to the main and auxiliary lights.

The NU25 uses a built-in rechargeable battery to reduce the size and weight of the unit and to create a compact and comfortable headlamp users can wear for hours at a time. When you're ready to recharge, simply plug-in the micro-USB charging cable into the built-in micro-USB port and any USB compatible power source, making this a great headlamp for travel and daily use. The headlamp unit can also be connected to external USB power sources via the built-in micro-USB port for extended runtimes allowing you to continue activities without having to stop and recharge.
