Digging up another old thread, I'm afraid, but it has to be done! [Linked Image]

This question is more specifically about CWI ballasts, but it fits best here I think. Since the only difference between the circuitry for an HPS ballast and a MH ballast is the ignitor, if you had an HPS ballast that you wanted to switch over to running an MH lamp could you simply remove the ignitor from the circuit? I'm thinkin in terms of retrofitting places that have the not-so-pretty(but slightly more efficient) HPS lighting but would look a lot better with MH lighting.
