Hi,, first grow. Just switched to 12/12 with a black lumii digital ballast 1000w. Veged fine with my 250w super veg bulb (dimmable ballast) When I went 12/12 first 600w black lumii dual spectrum bulb was a dud, got a free replacement and only got 2 shifts out of the bulb. I've had to use my veg light tonight on 12/12. Looking for advise if this black lumii gear is utter shite or mabey there's a chance it might be a dodgy batch of bulbs or ballasts?
