By physically pushing the arm to specific points around the circle's edge and adjusting the spotlights and floodlights in the ceiling, VPEL can simulate light conditions at every time of day from sunrise to sunset.
Prior to the development of the VPEL, the lighting team did the bulk of its testing by taking cars out on the road under different sky conditions to try and evaluate interior components and identify potential problems like washouts, but it was a time-consuming task.
According to Dassanayake, the VPEL has afforded designers and technicians the unique opportunity to test components faster and at a much earlier stage of development.
