There you are. As I was saying. Without a special ballast, US fluorescents would (did) flicker at 120 Hz,

But the ALL have 'special ballasts. You dissed CFLs because they have 60 hz flicker. I posted that they operate at 40Khz. There is NO perceivable flicker since they all have electronic ballasts.

Read my post again for comprehension. I wasn't talking specifically about CFL's, I was talking about fluorescents, of which CFL's are a subset.

You say they don't flicker; but you haven't proved they don't. You talk about ballasts with a higher cycle rate -- but do they not flicker at all, or do they flicker "imperceptibly", the way fluorescents on 410-cycle AC would?

Other people are posting info, you're playing games with posters.
