Boston, Massachusetts, USA

Philips Color Kinetics also noticed the dim lights and wanted to get involved in helping to revitalize the landmark. The company wanted to do something meaningful that would have a positive impact on the Boston community, where Color Kinetics was founded and where it has put down its roots.Philips Color Kinetics, worked with MassDOT to relight the bridge towers with a state-of-the-art LED lighting system, and helped them understand how the lighting industry's most advanced and innovative technology could reduce energy and maintenance costs. They also explained how MassDOT could also use digital LED lighting control to change the colors of the lights with the touch of a button for holidays and special occasions, and in the future to potentially indicate traffic conditions.In turn MassDOT shared the challenges they face to keep roadways, bridges, and tunnels safe and operating day and night. Relighting the Zakim Bridge seemed especially problematic: it would be costly to rewire for a new lighting system, and would possibly require excavation, lane closures, and disruption to traffic.Philips Color Kinetics introduced MassDOT to IntelliPower, a solution that leverages existing electrical and physical infrastructures to enable the affordable installation of dynamic, digitally controllable LED lighting systems. By using IntelliPower, MassDOT was able to use the existing wiring and fixture mounting points on the Zakim Bridge, which dramatically reduced the cost of relighting the bridge. MassDOT replaced the old metal halide fixtures with Philips Color Kinetics ColorReach Powercore LED floodlights.The new LED lighting system, which is estimated to reduce energy consumption by more than 80%, was unveiled in December 2012. Now the city's signature image shines brightly once again.
