Answer is yes that amount of light would give you good coralline growth.
Now a couple of questions.
Are your ballasts electronic or magnetic?
If electronic zoomed bulbs are great but will not work on magnetic ballast.
Can you fit 24 and 36 end to end?
I assume your hood is 60" long, I have 60 long also. My problem was I didn't have enough room to fit 24 and 36 end to end to get 60 length. End caps take up space. I went with 6 48" t8 and offset. i get plenty of coralline even have some low light zoos and mushrooms in tank.
Why not include your 4 VHO
bulbs in the plan?
