The Changing Shape of Light by Jim Axelrod, CBS News

Recently I saw this wonderful video about the need of incadescent bulbs replacement and the entry on the market of new led light bulbs. Check this video made by CBS News.

To find a solution, the U.S. government is offering a $10 million prize, called the "L-Prize," to the company that builds the most efficient bulb with the most pleasing light.

Philips submitted the first design to the L-Prize contest. The bulb features light emitting diodes (or LEDs), which used 80 percent less energy than an incandescent bulb and half as much as compact fluorescent lights.

It is clear that after more than a century, America is finally turning its most enduring innovation into the next bright idea.

  1. led light emitting diode are popular because they are low cost and maintenance and low energy consumption. To provide maximum natural light output, which requires a minimum force in fact, emit almost no heat....

  2. brilliant topic you have to talk with customer because we all want to get deck led lights for our facility to our self bright so i would like to appreciate you on this
