The Future of Light?
Photograph by Mark Thiessen

Workers expose colored LEDs, or light-emitting diodes, to high currents, temperatures, and humidity to test the devices' long-term reliability at a semiconductor factory in Durham, North Carolina.  Using nano-engineered molecules to emit light-generating photons, LEDs are energy efficient. According to a U.S. Department of Energy study, such solid-state lighting could replace traditional light sources over the next two decades and decrease U.S. energy consumption by nearly 30 percent.
