Abstract

CIE standard illuminant A was introduced in 1932 to represent typical tungsten-filament lighting in colorimetry, and for decades it has been used as a reference spectrum in photometer calibrations.

In 2018, CIE published new LED illuminants in CIE 015:2018 Colorimetry, 4th Edition. Based on one of the new LED illuminants, this Technical Report publishes a recommendation for an LED reference spectrum, named "CIE reference spectrum L41", for photometer calibration that complements CIE standard illuminant A. Specifically, this document includes the tabulated data of CIE reference spectrum L41 and a quality metric for selection of white LEDs for physical LED standard sources.

Information is provided about typical magnitudes of spectral mismatch errors with V()-filtered photometers in measurements of LEDs, as well as other types of light sources, when CIE reference spectrum L41 is used for photometer calibration instead of CIE standard illuminant A.
