Help with lights

[buwanna]

I have a 55gal reef tank that I'am fixing to buy T 5 lights for. The lights have 6 blubs which I have a choice of 6500k 10000k Actinic which comb would be best.

6500k have a greenish yellow tint to them, and the 10000k are more yellowish/ whitish. if you have six bulbs, i'd go with three 10000k and 3 pure actinic.

I am running 6 - 54 watt over my 90 gallon. I got 3 10k's and 3 blues. I am changing one of the blues to a 6500 to see how it look's when I get paid.
It doesn't have a yellowish tint at all. It is very bright white, I would compare it to two 150 watt Mh's.
