Re: Phil the Idiot Savant

This is the crux of what I referring to. For mass market CFL products the
physical size of the components needed to make an effective passive VAR
filter are too big and too expensive (relative to size and cost of CFL
products). Active PFC is readily available for switch-mode supplies and
small integrated PFC & regulator devices are in development (maybe even
available now) for CFL and standard FL ballasts.

the chinese will make whatever is asked of them. We the consumer could
immediately force the use of PFC CFLs, by refusing to buy non-PFC CFLs
(and telling the supplier why we wont buy them). But of course we
wont....consumers will buy whichever is cheapest.
I'm doing a PFC design for an electronic lamp now (not CFL). not for
unity power factor (although its required), but for maximum efficiency ;)
