I had great luck with 1 plant years ago don't remember what it was called Myrio? Grew probably 3" a day and that was just a regular t8 bulb. I don't have my light yet but I'm going to be using the fugeray LED. My only other options were a 15w t8 fixture or a dual t5 putting out 34w. And I would need CO2 at that point right?
