That is just the spec. graph. The green spike there actually neutralize the color of other spectrums. I have all 5000, 6500,6700,8800 and 10000K bulbs and 8800 is the whitest among all. It's really hard to tell the difference between 8800K and 10000K in a planted tank because the plants reflection makes the tank look slightly green. If you have them on top of un-planted tank with neutral or dark gravels, you could see that 8800 is the closest thing to pure white.
