Digital E ballast are well worth the money! If you get the right one.. I have a Hydrofarm Phantom 1000 watter. If I were you I would spend a little more on one that will honor thier warranty. Mine has a super warranty! Check out the hydrofarm ballast.. You'll be very happy with your investment!:thumbsup::jointsmile:

I might add that HTG is a great place! I order from there myself.
