Not all full-spectrum lights are the same

[Guest guest]

After we cleaned up our drinking water, our family is now in query for healthy lighting at home. The lights are just as confusing as the water machines in the market that apparently different manufacturers have different ideas about what constitutes a full-spectrum light source.

Furthermore, we found this article published by a university-based research center on full-spectrum lights:

http://www.lrc.rpi.edu/programs/nlpip/lightingAnswers/fullspectrum/abstract.asp

It suggests that full-spectrum light sources will not provide better health than most other electric light sources. "Short wavelength (blue) light is particularly effective at regulating the circadian system; long wavelength (red) light is apparently inconsequential to the circadian system. Thus, to maximize efficiency in affecting the circadian system, a light source should not mimic a full spectrum, but instead should maximize only short wavelengths. Even if a full-spectrum light source includes short wavelength light in its spectrum, it will not necessarily endure proper circadian regulation because, in addition, the proper intensity, timing, and duration of the light exposure are all equally important for satisfactory circadian regulation."

"One of the claims often associated with full-spectrum light sources is that they are most like natural daylight. Unlike full-spectrum electric light sources, however, daylight does not have a fixed spectrum. Rather, natural light varies with latitude, time of day, season, cloud cover, air pollution, ground reflectance, and, if a person is indoors, window tinting.... The infinite variety and variance of natural daylight spectra makes it impossible to evaluate quantitatively an electric light source in terms of its ability to emulate natural daylight.... Since daylight is a naturally varying light source, a light source that emulates one particular daylight spectrum is, by definition, unnatural."

We just initiated our search for healthy lighting. I am tossing this article in the group to see if any one has dived in depth on this subject and can share findings or experience of full-spectrum light sources or other choices of lighting. Thank you.
