The AJ lamp is designed among a lot of other lighting fixtures for the SAS Royal Hotel in Copenhagen. The standard lamp consists of a lamp holder in an enameled brass pipe, the dimensions and construction of which are reminiscent of his ceiling lamp in the council chamber of Roedovre. A tilting mechanism has been installed in the pipe. The angles of the conic metal shade are made so it flush with the lamp holder at the top. When the lamp is tilted downwards, the edge is horizontal. The inside of the shade is matte white enamel. The screening is effective, you cannot look up into the light source. Using a clear incandescent lamp the light is exploited the best way and the the light rays delineated preciesly.
The AJ lamp has a fixture head with a distinct asymmetrical shape, which determines the light characteristics of the fixture. The fixture head is tilt-able. The base of the desk lamp has a hole, originally made to accommodate an ashtray. Without the ashtray, however, the hole adds elegance and lightness to the design. The unique quality of its design idiom has made these fixtures modern classics
The Standard version of the lamp is slightly different from the original version with a more angular shade rather than a flat from top shade.
