Thats not bad with how far the light spreads on it.
Have you considered shop lights? I came across Simkar Reflect-A-Bay lights and had to have them for over my tank, in my equipment and utility rooms and in the garage. They are used in warehouses, etc., and are very bright. They come in 4 and 6 bulb configurations T5 and T8. They now have a Reflect-A-Bay LED light which was not available when I got my lights.
Mine are amounted two feet above the tank. Because they are so close to the top of the tank, I got the plastic cover to protect from splashes. We wired the lights on two switches so we can have two, three or all five lights on. In this picture, I had removed the plastic protector that was on the cover off only the first light.
My tank is 4' high and 4' wide. When I saw this light in a plumbing/electrical supply store, I had to have it. It stood out from all the other shop lights that were on display and were also on. Don't know how the price compares with other lights. I paid about $160 each for them, not including the bulbs. I never considered any other light. My backgrounds are not finished yet, so the tank is not set up and running. I went with 4100 K bulbs. Plenty of light for me.
I did consider using them but dont think I really have the space height wise to use them correctly. They are always a fall back option since they are always readily available.
But I have been dying to see that tank of yours completed! Your pacu are really going to love that
