Just wanted to let everyone know that if you want to save yourself money on conversion ballasts or leave yourself some options, you can just buy a HPS ballast and run either bulb. You cannot use HPS in a MH setup though. The difference is the HPS has an ignitor. Ive been using an HPS and MH in a dual 220v ballast for 3 months now and no problems.
