National Mall gets more efficient LED lighting

The historic bronze streetlamps that line America's front yard, the National Mall in Washington, D.C., are casting a new, more efficient glow. This week, they were retrofitted with LEDs (light emitting diodes), donated by lighting manufacturer Osram Sylvania and installed pro bono by the city's electric utility Pepco. The bulbs replace the Malls' high intensity discharge and CFL (compact fluorescent lamp) lighting. They're expected to use up to 65% less energy and last up to 25 years.
