Very good information. But this concept may add significantly to the price of LED lighting device.

This article briefs about the color changes in the LED light output over a period of time and how it can be controlled to have minimum perceivable to our eyes.The active color control techniques said here can solve this.The cost of the lighting will increase accordingly.The color sensors mentioned here also will age and this to be matched with the life of the LEDs. As such the wave length of light output from the LED varies as the operating current and the temperature changes.So it is a multi computational effect and the circuit design need to address this effect with good dynamic range.
