While those bulbs would give you more growth than any other bulb, IMO it's the crappiest look I've seen on a reef, and doesn't bring out the colors typically sought by people for display tanks. And once you factor in the amount of actinics to get it less fugly, you might as well go with the 400s at the color you like.
Iwasaki is a great frag grow out bulb, but not a nice looking color.
