Full-spectrum light sources may have psychological benefits, particularly in societies that place value on "natural" environments. 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. Nevertheless, it cannot be denied that people consistently prefer natural lighting from windows and skylights to electrical lights. These preferences are robust and may reflect psychological associations with the natural environment that produce ผลกระทบเชิงบวก in many people. Positive affect induced by daylight may, in fact, help improve mood and motivation and thus increase productivity and retail sales. Full-spectrum light sources offer this positive association with daylight. Although positive psychological benefits from full-spectrum light sources may have been observed in some circumstances, there appears to be no biophysical explanation for those observations (Heschong, Wright Okura, 2000). Still, the power of psychological associations cannot be denied and it is certainly conceivable that cleverly marketed full-spectrum light sources may provide beneficial effects to some people susceptible to that marketing. As NLPIP's survey demonstrated, there appears to be a strong positive association with full-spectrum light sources that has resulted from marketing, presumably because of the association between full-spectrum lighting and "natural" light.
