Good idea... Interestingly the 4100 and 10000 white look pretty much identical on my monitor. 6000 lucks yuck green, reminds me of the GE Starcoat one. Did you lock the white balance on your camera? If not, the camera will adjust somewhat and the results become difficult to interpret.
I would like to see a shot of all lit bulbs, side by side.
I know this is hard to do with only one fixture.
