NAPLES, Italy (April 5, 2016) Recently installed ight-emitting diode (LED) streetlights on Naval Support Activity Naples, with Mt. Vesuvius in the background, are now replacing conventional high-intensity discharge lamps for outdoor lighting. LEDs produce more light with less electricity and less money than most other lighting technologies. (U.S. Navy photo by Mass Communication Specialist 1st Class Daniel Barker /Released)
