New tank light

[SoloSK71]

So I am designing my new tank and have narrowed my lighting choice down to three.

Tank is 36" l x 30" w x 28" h and will be a mixed reef tank.

Light choices are:

1. Single Radeon XR30w G4 Pro (Ecotech has promised this will provide enough coverage)
2. Kessil AP700 w dispersion lenses
3. 36" ATI 8 bulb Powermodule

Obviously there is a significant price difference with the ATI, and it is the one I have no experience with, and I am looking for advice from my fellow reefers as to suggestions.
