Lighting Designer Daniel Knipper used 24 CHAUVET Professional Ovation Rêve E-3 IP LED ellipsoidals in his transformative design for the six-century-old Strasbourg Cathedral located in Place de la Cathédrale in Strasbourg, France. The full-spectrum color-mixing fixtures, which were supplied by XEOS, were hung on two porticos that flanked the façade. This  arrangement allowed Knipper to highlight the architectural details of the façade by creating gobos based on digital photos.
