In Manila, Philippines the Boni Tunnel in Mandaluyong is now brighter and more energy efficient thanks to a new innovative solar powered LED lighting system from Philips. Not only is great for the environment, but the city government of Mandaluyong also expects to save up to P240,000, approximately $550,000, every year in electrical costs.
The lighting system is expexted to save up to 51% in electricity expenses every year, and consists of Philips tubular LED lighting systems that will be solar-powered by day, and powered by the power grid at night. The tunnel lighting system is connected via a grid-interactive photovoltaic system with solar panels placed on top of the tunnel. The solar panels are connected to power converters, and then hooked up to the Meralco power grid.
