Mounting height Photon 48 V2

[ApoIsland]

Considering this light for a 120g 4x2x2. How high would I have to mount it to realistically attain the full 24" spread front to back? I have sps along the back wall as well as back corners. Have a clam and lps in front sand bed.

Thank you.

Hi, about 10-15" off of the water is the best height for these on a 24" wide tank.
