Philips Electronics of Burlington is behind the bright, ever-changing colors lighting up Boston’s skyline. The lights beaming off Boston’s Prudential Tower are LED lighting fixtures from Philips Color Kinetics.

Principals Steven Rosen and Bill Kadra of the Massachusetts lighting design firm Available Light collaborated with Philips Color Kinetics on design, integration and programming. More than 25 ColorReach Powercore high-performance LED floodlights were permanently installed on the building’s crown, saturating the local landmark with vivid color and effects.

The architectural floodlights can generate millions of colors without gels or filters. The color scheme can be changed on the fly to support local events, celebrate holidays or reflect the brand colors of individual organizations to promote their events.

"As a Massachusetts-based company, it is an honor to illuminate the beacon of Boston," said Jeff Cassis, CEO of Philips Color Kinetics. "This installation further demonstrates that LED lighting is a viable and energy-efficient solution for architectural floodlighting, providing vibrant color while eliminating maintenance concerns. We’re proud to add such a prestigious landmark to our long list of installations."

To show off the tower’s new light system, the Shops at Prudential Center started the ‘31 Nights of Light’ campaign this month, displaying colors of Boston-area philanthropic organizations each night.
