it comes with ballast and bulb at 46 dollars a piece not a bad deal

oh, nice! the ballast is in the back attached to a grounded power cord right?

Those 70w HPS bulbs can get hotter than a 150HPS. Do your best thow. Your cabinet door being sucked shut is fine, that is good negative pressure, but if it is to loud for you, then down grade. Also, you could add a passive intake that could help.
