Yeah idk about this one. I was always told to stick with name brands and brands that have proven themselves. I got my electronic balast from a hydro store in my town and the reason i got it because 1. it was a good price around 350 for two lights two ballasts and two bulbs and 2. because they gave a 5 year warranty on it. in 5 years it will more than pay for itself. just make sure you keep the receipt.
