Just go buy an Evergrow IT2012 or whatever
oooops
Not sure what your budget is but you'd only need one (48"). If you're concerned about spread you could maybe put 120 degree optics along the front and back row?
If you're just looking for color input I don't really like the look of 6500k LEDs so replaced them on my old light with different colours. I had algae for a short period running red LEDs, covered them up, added a couple more hermits and it was gone a short time later and never came back
And you could have sunrise/sunset if you wanna tweak the way your tank looks
