More than 780 special luminaires equipped with approximately 100,000 LEDs were used in this project. Thanks to intelligent lighting control, the lighting of the church, which covers an area of around 22,000 square meters, can be quickly and easily adapted to predefined lighting scenarios. With the new LED light, for example, the mosaics in the domes of the side aisles now can be seen down to the smallest detail. Numerous works of art that previously disappeared in semi-darkness now shine in all their glory.
“We are very proud of this lighting masterpiece in St. Peter’s Basilica,” said Olaf Berlien, CEO of OSRAM Licht AG. “The project demonstrates just how history and high tech can be combined in the best possible way by using the right expertise. More than 500 years of history are now being bathed in digitally controlled LED light.”
The innovative LED illumination with high spectral quality and efficient photometric distribution has significantly reduced glare. Due to their special geometry and compact dimensions, the luminaires could be optimally integrated into the architecture. The number of luminaires also has been significantly reduced thanks to their efficiency. Together with the digital control system, energy savings of up to 90 percent are possible compared with the old lighting.
