The manufacturer's reccomended height for the Hydra 32 is 8 -10" above the waterline. The picture and my old eyes make it difficult to see if there is coral in your tank. If there is, I would move them down slowly so that you don't shock anything and adjust the intensity accordingly.
They are mounted exactly 14 inches above the water line. This was tested to be the most even spread of light for the hydra 32 by brs. I do have corals I have one Acan and another sps can’t remember the name and have created a collection of lps and zoas. I had them at 30% as to not burn anyone since I haven’t had a par meter. Considering everyone has said 60-75% I have moved them to 50% for tomorrow I will rent a par meter soonThe manufacturer's reccomended height for the Hydra 32 is 8 -10" above the waterline.

You seem to have a ton of light spillage though. Did brs have the exact same tank as yours? Other wise I would lower them. Your tank seems pretty tall and the rock is pretty down low I don’t think you will have an issue if you lower them. I keep my lights 8” above the surface for the purpose of minimizing light spillage and having the light blasting my eyes because I personally find it quite annoyingThey are mounted exactly 14 inches above the water line.
