In December 2009, CMLC outfitted the Langevin Bridge with state-of-the-art LED lighting. The system is composed of 156 different light assemblies that highlight every beam and truss on the 110-year-old bridge. The lighting units are controlled by a computer program, allowing infinite display possibilities.
Despite a total of over 5600 LEDs being used, the lighting is expected to consume only 22,000 kilowatt hours per year, roughly the same as the power consumption of just three Alberta households. The LED lighting has an expected lifespan of 100,000 hours, which equates to approximately 35 years of operation if the lights run for eight hours every day.
Each assembly unit has the ability to display over 16 million different colours, providing the bridge with a shade for every season, occasion or celebration. Not only does the system allow for spectacular light shows, it also helps keep the area safe.
