I have 3 black boxes on a 125 gallon aquarium that do ok with lighting and coral colors. My first tank ran with T5 4 bulb fixture I liked the even light distribution and coral did good under it. I’m wondering if you get a big difference with a 4 bulb or an 8 bulb fixture other than intensity and being able to handle sps.
