The HK20 Bubi from Carl Hansen was designed by Henning Koppel in 1972 and is characterized by its curved, drop-shaped design. The lamp has a shade in opal white acrylic and a top and base in chrome or brass. It provides a soft, glare-free light and is well suited for illuminating smaller areas. HK20 Bubi can be used as a ceiling lamp, alone or in a group, and can be turned to function as a ceiling lamp as well as a table or window lamp.
