I'm curious as how long till the spectrum starts to change, if at all.

As far as ive heard, there isn't any spectrum change. I called up Cree and talked to a tech about it before I built my unit and he said as long as you don't over heat them, the spectrum will stay the same. Basically the shortened down explanation of what he said was that the compound that is used to give an led there specific spectrum is stable as long as it isn't over heated. So if you burn your leds to hot they can have a spectrum change because of the compound breaking down into something else Like the zinc based compound used in blue breaks down into something that makes it kinda purple when it gets really hot.
They aren't really line halides or t5 which actually burn a compound to create the spectrum.
Just what I've heard anyways!
