Nitecore NU25UL

'The ultra-light version of the NU25-400 features slimmer lines than the base model without sacrificing performance: powerful output, a weight-optimized design, a proven control system, USB-C charging and a redesigned headband. Its built-in 650 mAh battery delivers up to 45 hours in Ultra-Low mode and up to 2 hours 40 minutes on High (400 lumens). The headlamp uses three types of light: two main LEDs for spot and flood (with a mixed beam option) plus two red LEDs. The lightweight polycarbonate housing meets IP66 for dust- and water-resistance. The comfortable strap-style headband helps keep the total weight to just 45 g. A USB-C charging cable is included.'
