The Department of Energy (DOE) has instituted the "L Prize", a competition that challenges lighting designers to replace the commonly used 60W light bulb with the PAR 38 halogen lamp with ultra-efficient solid-state lighting products. A future L Prize program will call for development of a new 21st-century lamp that delivers more than 150 lumen's per watt.
So what does it all mean? The L Prize competition focuses on development and market adoption of a solid-state lighting replacement for the 60W lamp that uses only 10W - a savings of 83%. If every socket in the United States converted from 60W incandescent lamps to the 10W L Prize winner, the country would save 34 terawatt-hours of electricity per year; enough to power the lights of 17.4 million households (twice the consumption of Las Vegas). That also equates to 5.6 million tons of carbon emissions).
