Too fast shutter it fired, when there was no current section.
And i guess you are using CWA ballast - because this type has quite long "pause" between 120Hz "flashes". On HX transformer or series choke reactor you would not hit the really dark region, as it is too short.
When thinking about what ballast has the long dark "hole", i had the resistive type in mind, but i forgot, then it is actually used as well, in SBMV...
