LED streetlight project in London
London will get a large deployment of LED street lights by 2016, and through this project, the city aims to save 40% energy, and 60% cut down in carbon emissions by 2025. London will upgrade 35,000 streetlights with LED lamps in the first phase, and install a network of control systems to monitor the LED streetlights.
