I have a SF2000 and it does a good job over my 2' X 3' ebb & flow. It did not cover 2' X 4' tent even with a light mover. With any LED look at the PPFD map and not the wording, they all lie like most marketing people do. No I am not bitter, not at all. lol. 

The lights I use over the RDWC have HLG drivers, I agree with King on the HLG's, they are the leader in the industry. 

My first lesson on the new LED's these days is it is easy to fry a plant if your not careful.
