You are correct in saying that there is no PFO hqi. This is why when you run the PFO ballast they burn the bulbs out premature and cause them to look whiter. Radium will not honor any warrenties when using this ballast. I have a ballast coming to Canada this week that is going to be a hqi/ps 400 watt. This is the ballast that Radium recommends for their lamps. This ballast will give you 11-12 months of lamp life.
