Which red 630nm or 660nm should I add for blooming?

My room is 4x8 and I'm currently using two 3590x4=340w, with a citizen 1212 x 2=150w and bridgelux 250w x 2 in the middle. 3500k on the cobs and multispectrum on the bridgelux. Which red would serve me better for flowering, 630nm or 660nm? I want to add 150w on each side.

Since your cobs are not 90CRI, I recommend 660nm. The cobs already produce plenty of 630nm.
