there is some false info in that being that a 250 watt HQI ballast does not overdrive a bulb.

Also the part about two ignightors will fight each other and start a fire is totaly false.

I'm thinking I'll bite the bullet and get an electronic ballast, well its just the shear cost difference. I haven't had a chance to research the bulbs I bought so I still need to work out what type of ballast I need.
