The U.S. Department of Energy (DOE) has published the final evaluation report from a GATEWAY demonstration on Franklin D. Roosevelt Drive, a heavily traveled New York City freeway with elevated portions. Four different types of LED roadway luminaires—each from a different manufacturer—were purchased in 2009 and compared with the incumbent high-pressure sodium light fixtures. The [...]

From the people who brought you the LED Lamp Locator, Lighting Internet Technology Enterprises (LITE) recently announced the launch of the LED Fixture Locator, which provides access to updated information on thousands of LED fixture products from hundreds of manufacturers.
