How high to mount zetlight zt6400 above the water surface

[heavenkid]

Hii everyone, i just got myself a zetlight zt6400 for my 3 footer tank, 90x45x45cm.

I intend to get a mounting kit to mount the light. Any suggestion how high should i mount the light above the tank surface?

My substrate is above 5cm thick.

If it is adjustable, and it looks that way, it doesn''t matter that much. You will probably start on lower settings anyway, and gradually increase ( plantmass and CO2 permitting).
