Scientists from Dresden University of Technology in Germany have set out to build energy efficient organic LED (OLED) lights that could rival incandescent

The bulbs also are 80 percent more efficient than incandescent
Homes are currently dominated by incandescent
bulbs, and approximately two third of the world's lighting solutions in use are based on old, less energy efficient technologies", says Paolo Cervini - General Manager of Philips Lighting Middle East & Turkey.

That's why the inefficient incandescent

Under the program, which commenced in 2006, the government is replacing high energy-use incandescent
bulbs in homes and offices with energy-saving compact fluorescent bulbs donated by the Cuban government.
