LEDs Promise Brighter Future, Not Necessarily Greener

But, in a paper published Thursday in the Journal of Physics D, leading LED researchers from Sandia National Laboratories argue for a shift in that view.“Presented with the availability of cheaper light, humans may use more of it, as has happened over recent centuries with remarkable consistency following other lighting innovations,” said Sandia lead researcher Jeff Tsao. “That is, rather than functioning as an instrument of decreased energy use, LEDs may be instead the next step in increasing human productivity and quality of life.”…
