it's more complicated with optics and the fact you want to mix cool white and warm white and royal blue and blue which will lead to slightly different colours in different spots. When I built mine I did 4 rows of alternating cool white and royal blue. Each LED in the row is about 2 inches apart. The rows are spaced about 3 inches between them width wise. They are also the opposite arrangement if that makes sense. So if row 1 is WBWBWBWB then row two is BWBWBWBW and row three is WBWBWBWB with row 4 being WBWBWBWB. My 4 violets are spaced out evenly down the centre and the 4 greens and 4 reds are staggered front to back and length wise as well. I don't use any secondary optics on the violet, green or red so I get a pretty even spread from them.
