CHARACTERIZATION OF LIGHT SOURCES – LED 3000K / 4000K

In this new series light sources, surface characteristics and visual stimuli are characterized by unified profiles. Information about unified profiles to describe spectral data you can find here.

Below two phosphor-converted white LEDs are compared. Light with a Correlated Color Temperature of 4000K causes usually a more cool and bluish impression than light with a CCT of 3000K.

To describe the color rendering characteristics are fidelity index Rf and gamut index Rg according IES TM-30-15 given. For both light sources is a more detailed description of the color rendering properties according IES TM-30-15 method available via LinkedIn. Login
