Glass skylights allow daylight to penetrate into the almost 100m-long access corridor which follows the course of the former motorway tunnel. Artificial light from special recessed wall-mounted downlights is automatically added by the ERCO lighting control system as and when needed.

Downlights ensure glare-free general lighting on the public areas, while track systems enable additional spotlights and wallwashers to be freely positioned to suit the requirements of the particular exhibition layout.
