Lighting Science Group, a company which designs, develops, manufactures and markets LED lighting solutions, has announced that the company's Prolific series LED street lights will soon light the streets of Washington, D.C.

Compared with traditional high pressure sodium (HPS) street lights, the PROLIFIC LED series street lights are 50% more efficient, provide more uniform light distribution, increase light levels, and will save Washington, D.C. tens of thousands of dollars each year in energy and maintenance costs. The new light fixtures will be paid for from American Recovery and Reinvestment Act (ARRA) funds and will begin to be installed in early 2011.

The first of the new lights will be installed in alleys across the District, beginning in Wards 7 and 8. Eventually DDOT plans to install energy-efficient light fixtures throughout the city including all the alleys, streets, bridges, tunnels and underpasses, pedestrian walkways, bike and running trails.

In conjunction with Howard University Transportation Research Center, DDOT conducted a study and analysis of LED lighting products from a variety of vendors and manufacturers. The study involved the evaluation and analyses of photometric readings, fixture life, efficacy, aesthetics, color temperature, dimmability and compatibility with remote monitoring and control systems. At the conclusion of the Study, DDOT selected Lighting Science Group's PROLIFIC LSR-2 LED fixture as the preferred choice to replace the District's existing lights.

"With rising energy costs across world, cities like Washington, D.C. are looking for ways save energyLighting Science Group's LED products are an obvious solution," said Zach Gibler, CEO of Lighting Science Group Corporation. "The LED street lights provided will improve both the environment and the city's bottom line by delivering a 50% energy savings over HPS street lights and will last approximately five times as long. The Washington, D.C. project is another significant win for Lighting Science Group in the infrastructure market and exemplifies the clear leadership and high-performance capabilities of the Company."
