Researchers have conducted the first cradle-to-grave assessment of light-emitting diode streetlights and determined that the increasingly popular lamps strike the best balance between brightness, affordability, and energy and environmental conservation when their life span -- from production to disposal -- is considered. LEDs consist of clusters of tiny, high-intensity bulbs and are extolled for their power efficiency and clear luminosity.
