For the best biological impact, vertical illuminance on the
eye should be considered. The sensitivity of photoreceptors
for biological light effect is higher in the lower part of the retina,
so the direction of light and the spectral quality in blue areas
are important.
Synchronize circadian rhythm
Minimum 250 lux m-EDI vertically at the eye in indoor
environments. Light enriched in blue spectrum like daylight.
(DIN Spec 6760)
