I ordered one of these inexpensive fixtures and it has 90 degree optics , my current led setup has no optics.
How high above the water should I hang it ?

i think 12'' off the water but it also depends on how deep your tank is and what setting you keep the lights at.i kept mine at 100% and 12'' over time you can lower more say 10'' off the water.

My AI Sols are only 5" off the water but that's with 40 & 70 degree lenses.
