I completely agree 1 is way more than I need, but what I am trying to confirm is that 8" off the water is sufficient. I am ordering a tank mount for the light so I won't be able to raise and lower the light. I need to order the mount for the correct height out of the gate.

If you are talking about the custom Mitras Rack from Modular LED.ca I ordered one as well. I ordered the 8" version. GHL recommends ~7.9" ATW (20cm) and the 8" fixture would place the bottom of the lamp roughly 8.75 inches above the water line in my tank. That's where I have them hanging now and it is working well.
