>From the article:

What should be remembered from this work is as follows:

* White light enriched with blue is more effective than the standard
white light that is found in offices and homes for the purpose of
synchronizing the biological clock and activating the non-visual
functions that are essential to the correct functioning of the body.
It is thus not necessary to use blue lights or even LEDs to obtain
positive effects.

* The effectiveness of this light does not require high levels of
illumination as is the case in the photic approaches to the treatment
of problems with the circadian rhythms of sleep or seasonal affective
disorder (5,000 to 10,000 lux are recommended in these approaches.)
