i found a few ballasts on ebay that claim to operate both hps and mh lamps...if this is true it would obviously be the right thing to use...but it seems too good to be true...has anyone had any experience with these

Or, if you'd like to look at the whole selection of links resulting in a Google on "Switchable Ballasts":

Yes, they are true. Hps needs an ignitor, MH doesn't. What they do is add a switch to turn the ignitor(or might be capacitor)on and off. You could just buy a HPS ballast kit and add a switch to the ignitor to turn it on and off to save $ but if $ isn't an issue...go with the switchable!!! Hope this helps!

The only 600 MH's I've seen are THESE CONVERSIONS

that bulb will work on a regular HPS ballast with no issues as that's what it's designed for. I assume in a few more months the regular MH 600's will be out. You'll probably see an increase in Lumens with a traditional bulb over the conversion. Won't know for sure till it's out and we can compare.
