Seoul Semi Says New 'Sun-Like' LEDs Could Generate $400 Million in Sales by 2021

Leading LED maker Seoul Semiconductor announced a new technology which it says minimizes the blue-light spike emitted by regular LEDs that is commonly blamed for sleep disturbances and other health problems. The South Korean company said on Monday that the technology, developed in partnership with Toshiba Materials, would produce light more similar to the Sun's rays, capturing customers put off by the current quality of light-emitting diode (LED) lighting. LED makers, having cut costs to the bone, are now racing to improve the quality of the energy-efficient lighting as many consumers and organizations still favor the warmer quality of incandescent lightbulbs in regions where they are not banned.
