I have long suspected that 50(or60)Hz fluorescents somehow strobe with
the refresh rate of the display monitor. 60 Vrs. 72 Hz refresh on your
monitor *does* seem to make a difference (72Hz is better). Monitors
with 60Hz refresh rate under fluorescents at 50Hz seem to flicker.
(note: in Australia our mains power is 50Hz).

People come into my office and ask why it's always so dark!
