Vertex Illumina question

[asylumdown]

The more I read about these LEDs, the more I'm warming to the idea.

I practically salivate at the programmability of the Vertex Illumina, but I nearly choke at the price tag.

For a 34" wide and 30" deep aquarium, would one fixture be enough? or would you need two fixtures side by side to give you the right amount of coverage?
