Haven't heard anything about this, however it is good news. Fluorescent and LED light bulbs rely on phosphors instead of black body radiation. Human skin and eyes evolved (or "were created", for the Christians) to absorb wavelengths that are emitted by the sun and by fire. Phosphors are something that sea creatures and nocturnal insects are more adapted to. These alternative lights also have a flicker that a glowing filament does not have since the afterglow of tungsten maintains enough luminosity between electric pulses to provide a continuous illumination. Flicker is very stressful to the eyes and nervous system. Phosphor based lights generally omit the red end of the spectrum and and cause most people with fair complexions to appear grey and bloodless. Full spectrum and natural light has documented health benefits. LEDs are available in better colors than fluorescents, but they are made with rare earth elements, which China has lots of and we do not. China should NOT have a monopoly on our light bulb supply.
