EcoTech Radion placement

[b_newman]

I've finally decided to get 3 of the Radion LED lamps.

My aquarium is a 4x2x2' 120g with two glass braces and an overflow in the middle.

The attached image is not to spec because I'm not that bored, but it's close enough to get some opinions on how to position the modules if you can help please.

I have the same size tank and went with two Radions. I have them mounted with the controls toward the front of my tank (example 2 in your image, but with only two fixtures). I think any of the configurations you propose would work. Since they're supposed to cover a 2' x 2' area, I don't think it matters how they overlap.
