Hanging Radions

[tomlow617]

Looking for advice on hanging radions (Radion XR30w LED Light Fixture).

I am ordering two radions to put over a 90 gallon mixed reef tank. ( tank has center brace)

Assuming I want to
1) hang them from the ceiling
2) use a radion rail kit

I should -----

Hang them Lengthwise or crosswise? ( tank has center brace)

Which radion rail kit should I use, and what should the distance between the two radions be?

How far off the water/top of the tank should the bottom of the radion be? ( tank is covered with clear netting)

The following thread may give you some ideas http://www.reefcentral.com/forums/showthread.php?t=2156834

I would run the fixtures lengthwise about 8-9 inches over the water and center the lights between the center brace and the outer edges of the tank.
