? 20k ushio

I am currently burning 3 250 10k de ushio bulbs I was thinking after 2 years of mad growth what kind of impact I would get if I switch over to 20k ushio
 
And great color. I really like those bulbs. You can look in my gallery all the better pics are under ushio 20k.

How high are you running those bulbs from the water?
 
I had them at 8" off the water. I currently run the pheonix but will likly go back when I change out next.
 
I'm using the Ushio 20,000K bulbs as well. This is by far the best looking bulb I've ever used, and I've tried a lot. Growth is very slow. Oh well... you can't have everything.
