The circulation areas have been lit with 2,000 Chalice downlights. They provide a good first impression for the visitor and allow shoppers to quickly find the merchant that best suits their needs  among the 150 retail outlets, even at busy periods. The downlights were selected on the basis of their high light output in class and good colour rendering and cool appearance properties, which provide good daylight perception and transition through the space. Supplementary lighting for the atrium is provided by Sonpak floodlights.
