Nitecore NU25 UL Rechargeable Headlamp — 400 Lumens

The Nitecore NU25 UL is an ultralight rechargeable headlamp with a maximum output of 400 lumens. It uses a dual-beam system with a spotlight and a floodlight as primary lights, plus dual red auxiliary LEDs for night vision preservation and signaling.

The built-in 700 milliamp-hour lithium-ion battery recharges over USB-C in about 1.5 hours. Runtime reaches up to 45 hours on the 6-lumen ultralow setting, with 2 hours 40 minutes at the 400-lumen high. A power indicator shows remaining charge, and a lockout mode prevents accidental activation.

The headlamp is rated IP66 water-resistant and 1-meter impact resistant. It weighs 1.59 ounces (45 grams) including the ultralight reflective headband.

E-bike compatibility: USB-C charging works from any USB source, including an e-bike display USB port or a power bank. At 45 grams it adds almost no weight to the kit.
