I just updated my angel eyes with GP Thunder 8500k H8's. I had the 7000k on my X5 and really liked the look. These seem to be even more white - almost toward a bluish hue. Can't beat the price either. $18USD as opposed to $245 on the LUX. LUX would be superior, but this is a very close second to me.
The eyes on the left are stock, and the ones on the right are the GP Thunders.
