Lighting and controls is a huge, constantly changing, dynamic market. The ELECTRICAL CONTRACTOR lighting editorial listed below keeps current on technological innovations from LEDs, controls, and design to innovations in efficiency by traditional lighting formats. 

Over the last seven years, the LED Streetlight Replacement Program in Los Angeles has swapped more than 80 percent of the city’s 215,000 streetlight fixtures with LED units. To date, energy usage has lowered by 63 percent, saving the city approximately $9 million per year in energy costs.
