How weird, that black area in the middle of the blue glow. I'll do a mirror test like that with my K-x (white model also)
Though, here's a photo with some extreme blue light in a darkened lobby (you can view full size):

I suppose you can't get a better sample than that, the glowing cube, and the light casting on near by objects. Though, the blue cube was actually very smooth in real life, while in the photo, you ended up with a more solid blue with a harsh transition to the hotter areas. But I don't see any spots that turned black.
Same thing with the bright spots having more of an edge instead of a smooth transition to the vivid color in this purple background:

And this face lit by bright red had less contrast, making it look more flat than it really was:

But I'll do a test with that particular LED color and mirror. Who knows, it could be a side effect the mirror is causing. Don't know if mirrors have any special coating. Or could the LED glow, refresh rate, or whatever, have an odd effect during the exposure? Maybe try different exposure lengths.
