Arne Jacobsen designed this fixture, among many other features, for the SAS Royal Hotel in Copenhagen, in 1957. The wall lamp yields a pleasant downward directed light with its white painted inner shade. Furthermore, the shade can be tilted to adjust light distribution.

The AJ lamp family is considered to be the design Jacobsen is most famous for worldwide. Apart from the AJ Wall, the AJ family consisted of a table lamp too, a smaller table lamp, a floor lamp as well as a table mounted lamp that were all to be found around the SAS Royal Hotel after its inauguration in 1960.

The clean distinguished shape of the AJ Lamp with its immaculate light could be seen all around the hotel in copper and stainless steel. Together with the AJ Royal, the AJ lamp family was part of the overall design concept, which Jacobsen had created for the hotel. He practically designed everything himself. The parallels between the straight lines and the combination of straight and curved angles in the AJ lamp design are also visible in the geometric contours of his buildings.
