Gu10 Bulbs

[Mathew18]

I have an Aqueon Evolve 8 and i am going to upgrade the lighting with some GU10 3 watt bulbs. I was looking at doing 4 blues and 2 whites and was wondering if that would give enough coverage for a 12Lx9Wx12T area. I am wanting to grow everything from zoas to sps. Also would this ratio give the look of 14-20k spectrum? I saw some bulbs that have 2 reds and one blue and was thinking about getting one of these as well. And advice would be appreciated.
