Has anybody here added an ignitor to a standard MH to use CMH lamps? It looks as though not recommended by manufactures sites there is very little difference in ballast design. There was mention of voltage regulation on a few site, however, I am skeptical of this as they make reto-fit lamps to run in HPS ballasts. An ignitor costs only about $20. I have a abundance of MH ballasts. I want to run the Ceramics. I have seen the spectrum and I am convinced, they are the best lamp for veg and supplemental for flower. I think I will buy the ignitor this week. Any thoughts?
