I think this gets a lot of exaggeration. Although strobing occurs very
occasionally, the thing still doesnt look like its stationary, since
the fl tube gives out light over a fair percentage of the half cycle.


That only happens with mains frequency fluorescents *- and only with crude
tubes.

I dont think I've ever encountered a domestic/commercial/industrial
tube that doesnt produce 100Hz output when run on 50Hz. Are you
thinking of a special purpose type?


Modern electronic ones run at such a high frequency that strobing
won't be apparent. Or use high persistent tubes.

Or realistically, dont worry
