This is a pair of table lamps manufactured by Kaiser Leutchen. They are made of black chrome and each has an E27 socket. The lampshade has a diameter of 27 cm, the base has a diameter of 17 cm. Due to the ball joint, the lampshade is very flexible. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
