Los Angeles’ LED Street Lighting Energy and Efficiency Program is the largest environmentally-friendly LED (light-emitting diode) lights project ever undertaken by a city. Launched in 2009, the City aims to replace its 140,000 streetlights during the five year program. To date, over 36,000 LED lights have already been installed. This program is implemented by the Los Angeles Bureau of Street Lighting.
