This is a desk lamp by Kaiser & Co. (also known as Kaiser Idell), designed by Christian Dell, who was the head of the metal workshop at the Bauhaus! Both the base of the arm and the shade are adjustable. As it is an old item, there is considerable wear and tear, including paint peeling, rust, and scratches on the shade surface, as well as on the arm and base paint. However, this adds to its unique character and presence. Please understand that this is a rare vintage item before purchasing. Shade diameter: approx. 16cm Height: approx. 48cm Base diameter: approx. 18cm Socket size: E26 Cord length: up to 150cm * Removing the screw on the back of the base with a screwdriver allows for some length adjustment. * The power plug has been replaced with a National brand plug since purchase, making it usable in Japan. * Light bulb not included.
