The variability of the CRI among white light lamps obtained by mixing the light from multicolor LEDs (e.g., R, A, G, B or R, G, B LEDs) is reduced and the absolute value of CRI is increased by selecting the LEDs for each color to have a minimum difference and/or distribution of peak wavelengths, such as by choosing the LEDs from selected pre-sorted bins of LEDs having a designated range of peak wavelengths for each color. |
