Radion G6, I still think they are hard to beat especially if you like to see detail on your corals and good color rendition on your fish. People these days who are rating lights on a narrow subset of primary wave lengths used for photosynthesis I presume do not appreciate the beauty and detail of coral shape and form and just want blue. I wanted more par than spread so the narrow angle lens pumps that back up but if you are working with LPS or mixed then the standard lens gets you a lot of coverage.
As for Straton X they are a nice slim design with good output and no fans. The App is definitely G1 but they have said this version will get you up and running and do the basics you need, with more of the nice to haves coming in later editions
