If I buy a cheap 600W digital Welthink ballast for some guy in the big city who has got these from china obviously, are these a half decent ballest now, he says there UL tested is that true? Anyone growing with these i would like some info. I'll save $300 if I buy this over a lumatek! i could buy 2 of these and still be cheaper then the lumatek. what i'm worried about is the quality of the bulb. Any help would be appreciated.
