This rare mid-century wall lamp by Louis Kalff was made by Gebrüder Cosack Leuchten in Germany and is in perfect original condition. The shade can be rotated and tilted through almost 360º, making this lamp very practical for all kinds of uses. Thanks to the original wall bracket (inside), easy to mount. The main axis of the lamp is telescopic in a range from 120 to 170 cm from the wall. The poulley weight makes the movement easier with the cable so it slides easily. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I 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.
