they do make a conversion bulb for a 250 watt.. i bought one about a year or so ago.. its an eye hurtilux brand, and i think it ran me around one hundred bucks for it.. you are right though, not many companies make conversion bulbs for the 250 watt, i really had to scour the net to find the one that i bought.. most companies only go as low as maybe six or four hundred watt bulbs in the conversion style, but eye hurliux makes the conversion bulb for the 250 for hps for an mh ballast..

This is true, I am doing it atm on my 600w setup. The Mh is abit louder on start up and can be scary at first but it's perfectly fine. While we're on this note, my Mh bulb seemed to blow the usep in the ballast plug were as the HPS didnt so you might have to change the fuse to a higher amp if this happens. Your ballast has an internal fuse anyway so dont worry.
Let me clarify you can run a MH bulb in an HPS ballast (same wattage of course) But not the other way around. A HPS bulb will NOT fire in a MH ballast.
-HPS bulbs use an igniter to light whereas MH bulbs dont. HPS ballasts are built with the igniter & MH ballasts are not. HPS bulbs wont fire in an MH ballast because it has no ignoter. Conversion bulbs are necessary for the MH ballasts to run HPS bulbs. Hope this helps guys lmk if u have questions. I have worked at a hydro shop for over 7 years & know this because of experience.
