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