One LED Light Source is a practical spare light source that fits various Frandsen portable lamps, including Pila, Ami and Grasp. Unlike traditional battery-powered lamps that require the entire unit to be charged, with One you simply remove the light source from the lamp and then charge it with a USB cable.
One is equipped with an energy-efficient LED light source and a built-in three-stage dimming function. The One light bulb is perfect if you always want a fully charged light source for your Ami, Pila or Grasp lamp and is equipped with a battery that lasts up to 12 hours between charges.
