Wanting to achieve controlled conservatory-like conditions, the curators decided to use artificial lighting virtually exclusively throughout the exhibition and to darken the gallery's existing skylights. To augment the existing stock of ERCO lighting tools, the gallery purchased several hundred additional Eclipse wallwashers, which are now mounted on the existing 3-circuit track layouts. Their special lighting technology ensures that the vertical surfaces are illuminated with optimum uniformity. Low-voltage halogen lamps provide excellent rendition of the colours and their brightness can be regulated without problem, while UV and IR filters protect the artworks from the harmful components of light.
