(Karlsruher Institut für Technologie (KIT) ) Researchers of Karlsruhe Institute of Technology have developed a novel, even more economical LED street light. They replaced conventional high-performance diodes by a special array of weaker LEDs and, thus, succeeded in reducing power consumption by another 20%. As a result, CO2 emission is decreased and municipalities might save millions of power costs. Pfalzwerke Netz AG, the local utility company, for the first time equipped street lights with the new light heads in the municipality of Maxdorf, Rhineland Palatinate.
