Lighting height

[Newbie1]

My tank is 4 ft long, 2 feet wide and 16 inches deep. I have two “Ocean Revives T247”.

I want this to be a general multipurpose salt water tank.

What should be the height I set the lights.

Thank you

Well the or t247 has a 30" spread at 12 inches above the water you could raise it to get 36" of coverage but that would affect par for sure par map your tank to make sure you are getting the light saturation and par levels you need or you could suplement the dark areas with t5s.
