Produced by original hanau (ges.m.b.h., germany), this extremely rare klein-höhensonne s100 model is a true icon of early modernist industrial design. the piece embodies core bauhaus principles—geometry, function, engineering clarity—and its pale jade-green lacquer recalls the metalwork philosophy of marianne brandt, who produced similar spherical forms and mirrored interiors within the bauhaus metal workshop. this example has been sympathetically rewired so it may now be safely used as a standard table lamp while preserving all major original components, including the mirrored interior, hinge system, and internal plug storage. design & features striking pale green lacquered steel sphere, composed of two hemispheres the sphere opens on a midline hinge, mounted to a bracketed steel support bolted to the base; this bracket also functions as a carrying handle beautiful, authentic variation of green shades across the components—typical of early german industrial production when opened, the sphere reveals: • lower half: a circular mirror designed to intensify and direct the light • upper half: an aluminium concave reflector plate that focuses and channels the beam original internal compartment below the mirror, designed to store the wiring and plug; this feature remains intact and the original plug still fits and clips into place wiring now exits from the back for modern usability while remaining hidden inside the sphere when stored uses a standard e27 bulb (led, incandescent, etc.) the original medical bulb is included as a collectible historical piece supported by a curved steel arc rising from the circular base a rare, sculptural bauhaus object that foreshadows the spherical designs of the 1960s space age movement condition excellent vintage condition, especially for its age no dents to the sphere or base light signs of age consistent with a 1920s–1930s medical instrument hinges, opening mechanism, and mirror interior all in very good condition fully functional and in working order as with all vintage electrical items, a professional check is advised before installation electrical fits any e27 bulb original medical bulb included (non-functional, for display/collecting only) designed for 200–260v wiring is neatly hidden inside the lamp when not in use, as originally designed dimensions height when open: 40 cm (15.8") height when closed: 28 cm (11") diameter of sphere: 24 cm (9.4") diameter of base: 28 cm (11") cable length: 240cm (94.5") weight: approx. 3.4 kg this piece has an attribution mark, i am sure that it is completely authentic 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.
