The potential to exploit LED light bulbs to be used as sleeping aids stems form the fact that LEDs can be programmed to emit light at precise colors,tones and wavelengths."An LED is a light source,but it is an infinitely controllable source,"said Zach Gentry,an executive at Enlighted.Dr.Brainard's future predictions include that over the next decades health benefits will also be one of the main considerations when choosing a bulb,along with energy consumption,aesthetics and brightness.For more on Dr.Brainard'research visit:NYTimes.com's article by Michael Kanellos'A New Use for LEDs:Mind Control'.
