aging LED color

[sappyg]

not that i have noticed but i was curious if anyone has. is it possible that LEDs could or would become warmer in tint as time or use occurs.
i ask because i've noticed quite a range in tint which i am sure has more to do with the bin. but, this leads me to wonder if any of you have experienced this at all or have experimented with this question.

the only one that has a noticeable shift in tint is my Infinity (non ultra), its now less blueish. as for other lights i may not have given sufficient 'mileage' to notice the shift yet. :candle:

Some of us have had Cree's go from cool white to very yellow/warm tints. I have 1 Cree that has done this, with the silver backing, so there may have been a bad batch. My Cree die went from the light yellow color, to a dark/brown yellow color, so it appears to be burning up or something.

The only LED's I've noticed tint shifts on have been the 5mm whites, and they all seem to go bluer as time passes, not warmer.
