Pentair guideline is to aim for 4 lumens per square foot of pool surface. For example, if the pool is 500 sq-ft then you need 500x4=2000 lumens

This manual says the Colorlogic 320 lights ae 1100 lumens. Your pool is 600 sq ft and would require 2400 lumens. So 4 lighst at 1100 lumens each sounds like it will be plenty of light. Especially with a light finish.
