• The Nitecore NU25UL is a variant of the NU25-400, it differs by a different headband and slightly smaller housing, therefore also by a significantly lower weight. 
• USB-C charging port and new headband.
• The Nitecore NU25UL has three different light sources, two main LED's for spot and flood light (mix mode possible), as well as two red light LED's. The lamp is connected to the headband by means of a novel receptacle and can be easily and quickly separated, e.g. to clean the headband.
  
• The intuitive operating concept has been adopted from the NU33.
• A simple strap headband and the smaller housing reduce the weight of the NU25UL to only 45g.
  
• The Nitecore NU25UL features an integrated 650mAh Li-Ion battery that can be charged directly in the lamp via a USB-C port. A battery level indicator informs about the charging status of the battery.
