Very similar to Hans Agne Jakobsson's and Carl Thore's lamp configurations these white tiered hanging lamps were designed by the danish architect Knud Christensen in the late 1970s. Depending on the lightsource (LED or regular bulbs and wattage) they can diffuse light both warm and cold as illustrated in the photos. Measurements: H: 22 cm, Diameter: 16 cm. The set comes tested and installed with 2x3 meters new white cord and bulbs. 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.
