Battery-operated Tribun LED table lamp with 3-step dimmer The Tribun LED table lamp can be used throughout the home as an additional light source, as it is powered by a rechargeable battery and therefore only requires a socket for charging. Made of polymer and acrylic, the cylindrically shaped light is equipped with warm white LEDs in a satinised diffuser in the centre of the lampshade. The table lamp with touch function can be switched on and off by touch and switched to three brightness levels. A USB charging cable for charging at a socket is included. Once the batteries are fully charged, the light lasts up to 8 hours at maximum brightness.
