Brighter LED Lights Could Replace Household Light Bulbs Within 3 Years

ScienceDaily (2008-01-10) -- Researchers are developing new technology that could replace the household light-bulb within three years. Light Emitting Diodes (LEDs), already used in electrical equipment such as computers and mobile phones, are several times more energy efficient than standard light-bulbs. However, because of their structure and material, much of the light in standard LEDs becomes trapped, reducing the brightness of the light and making them unsuitable as the main lighting source in the home.
