Mitras Lightbar purchase advice needed on quantity and model

Hi,

I have a 300cm long, 62cm deep and 80cm high sea water aquarium which I would like to equip with Mitras LED Light bars and a Profilux computer.
The aquarium will be mixed reef with fish.

I am looking at 150cm long light bars and currently opting for 4 total, would that be sufficient?

Then I am having a hard time deciding what colors I need.
At the moment I am opting for 2x Ocean Blue and 2x Deep Actinic which I believe would give me the broadest light spectrum. Would that be the best choice?

Thanks a lot!

Leon
