Circadia Group served as program manager for the lighting restoration of Princeton University Chapel, a Nationally registered Historic Place. The project involved upgrading all 58 original Yellin Chandeliers — designed by Samuel Yellin and installed in 1928 — to LED with a modernized lighting control system. Circadia provided technical advisory, coordinating all stakeholders throughout the process, keeping disruption to a minimum, and delivered the project on time and on budget. Our team also negotiated warranty and reprogramming with the vendor and continues to provide ongoing technical support for Chapel and Facilities staff.
