As for separate electronic ballasts, they've all been PF 0.9 for
probably a decade or more. Once the design and initial roll-out is
done, there is next to no additional cost anymore. These products
are extremely high margin anyway - the component costs are tiny
compared with the selling price.

Presumably the same is not true for PC PSUs? Only the expensive ones
have proper active PFC.

I just checked a few budget ones I have in the cupboard - all of them
claim to have PFC
