During winter nights in Alaska, streetlights often remain lit more than half the day, using energy all the while. Around the nation, communities are exploring the use of
light-emitting diode technology for lighting streets and reducing energy use. Already, LED technology is successfully used in flashlights and electronic billboards. Some
researchers suggest that, under ideal conditions, an LED streetlight system might use 50% to 75% less energy than a traditional streetlight system, with a longer
performance life, too. In general, LED devices tend to be less fragile, switching on and off quickly, without flickering. LED technology, which may be the next step in
efficient indoor lighting after fluorescents, is moving into the municipal streetlight market as a possible alternative to high-pressure sodium lamps. For this reason, AUTC
researchers at UAA are exploring the use of LED streetlight technology for the Municipality of Anchorage.
