your lag bolts should be fine but get a heavy duty lag bolt if your worried. also use a chain to hold it up. plus u should have no vibration on your light & the ballast does not vibrate either. place your ballast on a shelf near by, the cord is long enough. the only vibration u should have is in your exhaust fan which i would use bungie to hold up.
BudLuv420 Reviewed by BudLuv420 on . ? on hanging a ballast I have a 1000 cropmaster ballast , weight 44 pounds- I have a 2x 6 ceiling joist which I have put a 4X6 bridge block between joist- I have a solid mounting surface- If I put in lag bolts how do I suspend with bungie cords as has been suggested in stickies. A lot of weight and I do want to rubber mount for vibration if I can!!Do not want this thing to come crashing down from 8 foot high Rating: 5
