It may not be possible to get that many lights over the tank so if you're going for a high light tank you may want to look for Power Compact (PC) lights. Is this for a freshwater or saltwater tank? If it's freshwater 10,000K is a bit high and will likely lead to algae issues. You'll want lights in the 6700K range for best plant growth. ^_^ [hr width='40%'] "Ah, yes," said the toad.

Freshwater plants do just fine in the 5500 to 6700K range. Much more than that and the algae uses more of the light than the plants do. You can try it and replace the bulb if you're finding you have too much of an algae problem. ^_^ [hr width='40%']"I'm alright, I'm alright It only hurts when I breathe"
