    What quality processes guarantee the consistency of the color appearance of LEDs?

    LEDs are standardized for consistency in color and performance through a process called binning, and they are classified further in the MacAdam steps. During the manufacturing process LEDs are allocated to specific 'bin' numbers based on tests conducted to determine their color, lumen output and forward voltage. LEDs from each bin are further classified in a 7-step MacAdam ellipse.
