I don't see how you can say this. LED life is now most
often specified as the time at which they have lost 30% of
their initial output. That's worse than most T5 and T8
fluorescent lamps, and would be a considerable challenge for
any color matching system.

My apologies. I wasn't clear. I was referring to instantaneous decay, not
light output depreciation over life.
Some LED systems already incorporate feedback circuits to compensate for
color shift and/or light output depreciation, of course.
