Submission + - Researchers Developing LED That Mimics Changes in Sun's Light (ecomagination.com)

MatthewVD writes: "The sun's intensity and colors change throughout the day, so why do we put up with lightbulbs that always stay the same? Lighting researchers are working on "universally tunable" LED bulbs that could change color and their perceived temperature throughout the day to mimic the sun. These tunable bulbs could have health implications, since research suggests that the wrong type of light can actually jet lag us or keep us awake. As LEDs drop in price, the more exotic applications could become increasingly common."
