The CIE recommended daylight illuminants in 1967. These daylight illuminants
contained ultraviolet radiation in proportions as found in natural outdoor daylight.
Indoors this daylight is filtered by the transmission of the window glass; therefore it
became necessary to define spectral power distributions also for the indoor daylight
phases. The TC recommends adoption of two indoor daylight illuminants ID50 and
ID65, that correspond to the phases of daylight of about 5000 K and 6500 K
The publication is written in English, with a short summary in French and
German. It consists of 22 pages with 5 figures and 2 tables.
correlated colour temperature. Tables of the spectra are provided at 5 nm intervals
from 300 nm to 780 nm, along with the rationale for their development and detailed
comparison with existing daylight illuminants.
