I have a pair of the 55W GE 9325K bulbs (which are obviously danged close to 10kK bulbs) in a 4ft strip light....

This is a textbook case of Kelvin rating having little to do with actual light color. While the typical 10000K bulb will put out a very stark white light, the GE 9325 is very pink/purple. This is very evident with light spillage onto walls.

What I've used over my 40gal breeder are 8800K 96W PC bulbs. Still a white light, but a little less harsh than the 10000K tubes I tried previously. I agree that 6700K tubes tend to have a yellow cast to them.
