Looks like I came up with a new creative way of messing up emitters.
While unsoldering a USWOH emitter from the star (something I've done a few times before without any problems), I managed to drop it on the floor while it was still hot, and it landed on ceramic tiles slug down. I'm guessing the shock dislodged the die from the slug or something, because this emitter now will not handle more than 400mA of current before the output starts shifting blue. At anything over 500mA, its color is comparable to that of a blue Luxeon, just not as bright
Just wanted to share.
