The small AJ pendant (ě370) was developed to hang high thus the light is diffused through an opal acrylic base plate, ensuring 100% glare-free lighting. The large AJ Pendant (ě500) was developed to hang low and therefore this products is not fitted with a diffuser in the original incandescent version. The T-R5 version is fitted with a plate to avoid unintended glare. The open rings at the top faintly illuminate the fixture. 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 products have achieved design icon status today, and the AJ lamps in particular among the lighting products have become world renowned. Bulb excluded 1x100W E27.
