Of the same brightness in all compass directions. Convention assumes that if a building is designed for daylighting according to the CIE Overcast Sky conditions then, when outdoor illuminance is brighter, the natural lighting performance will be significantly better. It is assumed that the minimum yearly average outdoor illumination is 5, 000... See #5.

An Explination Of Scotopically Enhanced Full Spectrum Lighting By Light Energy Source
Pupil size changed with both light level and the type of spectrum illuminating the subject's eyes. However, when the average pupil size variation was compared with the test illuminance variation at the eye (measured with a conventional light meter) there was no correlation. On the other hand, a near perfect correlation was obtained when... See #6.
