No, that's not safe, assuming you're talking about MH. The bulb won't survive, and might start a fire.

I diagree. Ran a 250 for over a year on a 400 ballast. I switched out the ballast because the color of the bulb was way wrong but no, no fire or explosion.

true. it CAN work. not that safe tho. you cant put a 96W bulb in a 65W ballast. try to experiment with something cheaper, and then decide if you want to try it with MHs.
