Take this into consideration! Hydrofarm waited and was one of the last to produce a digital ballast. With that being said..

They had a chance to see all the others mistakes before producing the phantoms. So it would seem to me that everything they used to manufacture these ballast were going to be Top of the line. You would think that Hydrofarm would have been one of the first to produce one. Not! They did the right thing by waiting as to get all the components of the best quality and build a better ballast.
