Not all CCT values are equivalent

In the diagram, you can observe iso-CCT contours for various correlated color temperature values. These iso-CCT lines connect points sharing identical CCT measurements. For the 3000K isotherm, note how this contour originates from greenish hues in the region above the Planckian locus, then progressively transitions to pink/magenta tones as it extends below the blackbody curve.

Coordinates may vary along the 3000K contour

Understanding 3000K CCT Variations

This demonstrates that when a luminaire is specified as 3000K CCT, its chromaticity coordinates may actually reside at any point along this 3000K iso-CCT contour.

2700K–6500K spectrum offers 13.68× greater color coverage

Expanding the Range of
Human-Centric Lighting

In current human-centric lighting applications, the main operating range is 2700K to 6500K. Compared with traditional standards, the color gamut coverage can actually be expanded by 13.68 times.
