I can't really compare them for you as I own a hydrofarm designer 2ft 8bulb panel.......But i do believe both bb and fluorogrow premiums run racehorse ballasts, but the quality will be better than BB IMO, according to some growers on here the BB tend to be flimsy, and always buy to smaller panels instead of one large one as stated numerous times in this thread......They are coming out with a 2 ft wide 4 bulb panel soon (according to Dennis/marketing) due to the large requests for it in their web poll, so maybe wait for that..........good luck
