The growers that have swithced all love them, I have been looking into them as well. For me Im just not so sure of the white light LED's I Personally thing the purple or ping glowing LED's have a better range of spectrum, its probably the hardest desicion we as growers have to make so it has to be right and every year new and better ones come out. It took me weeks of recearch before I decided on G8 lights glad its over haha
