Abstract:
A lamp having improved color quality scale, especially at elevated color temperatures, is provided. The light generated by the light-emitting elements of the lamp, when the lamp is energized, has delta chroma values for fifteen color samples of the color quality scale within select parameters. The delta chroma values are measured in the CIE LAB color space.
