I got got a 1000 what hps system 2 years ago , came with the hood,bulb,cord,ballast,all that shit. Got home a week ago my light was out thought it was my bulb so I ordered a new one got it today put it in didn't work. Wtf? What do you guy think it could be? My ballast sounds like its on, it hums like my olady. Do the cords from the ballast to my bulb go bad? Any input on this would be greatly appreciated.
