This very rare desk lamp from Kaiser Leuchten is also known as an architect's lamp because its extra-long arm can illuminate large construction plans, for example. Thanks to its small but rather heavy base (13 cm diameter), the lamp remains stable even in an extremely low position. In the vertical position, the lamp has a height of approximately 73 cm. The shade has a diameter of 17.5 cm. The socket is suitable for E27 bulbs. The lamp is a good example of the timeless and functional minimalism in the Bauhaus tradition, to which the Kaiser brand has always been committed. 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.
