The galleries were also critically reviewed as part of the renovations, and some have been rearranged or redecorated. Careful attention has been paid to climate control and lighting.
The new lighting in the galleries was the responsibility of Georges Berne of the French company L’Observatoire. He is a leading figure in this field and previously designed the lighting in the Louvre (the Richelieu wing) and the Musée Picasso in Paris.
Berne's lighting plan for the Main Building and Kurokawa’s Exhibition Wing strikes a perfect balance between artificial light and daylight in the illumination of the works. The very latest equipment is used to achieve this. Most of it was made to measure for the museum.
At some points lamps made by Tailored Lighting Inc. which reproduce the spectrum of daylight were added after the reopening. This technology did not become available until after the renovation of the museum and is now being used where possible.
