Designed by Arne Jacobsen in 1960 for the SAS Royal Hotel in Copenhagen (Radisson Blu). The light contributed to the total design concept of the hotel. Several of the hotels items have achieved iconic design status today, and among the lighting products the AJ lamps in particular have become world renowned. Five new color variants were introduced in connection with the 50th anniversary of the launch of the AJ family. The new colors have been carefully chosen in line with an updated Arne Jacobsen color scheme.

The 2024 anniversary edition features a brass stem and the shade is painted pale rose on the inside, which provides a soft, warm light.
