I'm sure it would work. But like the other poster said, its not going to have enough amps to drive a 430w bulb to its full potential. I know a guy that runs 400w bulbs in his 1000w ballast.lol Swears by them.
killerweed420 Reviewed by killerweed420 on . 430watt hps bulbs on a 400 watt ballast.... Im currently running a 400watt lumatek digital ballast with the stock bulb it comes with and it seems pretty weak. kinda looking to upgrade. I was told by the lady at the hydro store that you can run a 430 watt bulb on a 400 watt ballast with no negative/adverse side effects. Is this true?? :hippy: Rating: 5
