The PF of domestic electrical / electronics including lamps is irrelevant.
It may become relevant in commercial use, when large number of items are used at the same time - like hundreds of CFLs in an office building.
Then it limits just how many lamps can be on the same circuit.

I checked some household appliances (lamps, tv, laptops) with one of those Kill-a-Watt meters some time back.
They register both watts and power factor. Power factor was often very low, in the .6 range. CFLs and LEDs were both very low.

possibly- I\'ve not run noises tests on a kill-a-watt meter to see how
easily they are confused. I did just get a Vector Viz digital wattmeter,
circa 1986 and even a load like an electronic ballast shop light confuses
its voltage readings. It might need to be serviced though.
The general rule in the US is a circuuit cannot have a steady load of to
more than 80% of the rating. That is a 15 amp circuit off your breaker
should not run anything that needs more than 12 amps continious.
They\'re that terrible, contrast does drop if you use them somewhere hot
though.

If I understand correctly, I pay for actual watts, but wire capacity has
to include the extra. Presumably code requires sufficient headroom.

Kill-a-Watt meters are designed badly, unless they\'ve improved them
recently. With bifocals you can only read them in one orientation and
often that is not how you plug them in.

I remember that very strong magnets were once supposed to slow meters
down so I borrowed a very strong ceramic magnet from work to try. I
put it next to the meter and it didn\'t have any visible effect at all.

Power utilities are not unsophisticated, at least around here. We installed mini-splits in early January covering two floors of a 3-story, 5,000 s.f. center-hall colonial build in 1890, and substantially enlarged in 1928. In mid-May, the utility (PECO) sent a gentleman around to check both our electric and our gas meters. Our electric bills had dropped by a few percent, but still dropped, and our gas consumption had dropped by 2/3. The gentleman took one look at the outside compressors, and made an \'all-is-well\' notation. It is now mid-June, has been quite hot, but our electric bill is now the one down by 2/3 from last year, with our gas being nearly the same as we still cook, use hot water and dry clothes.
Moral of the story - if your established (11 years for us) use pattern changes suddenly and significantly, the Utility *will* notice.
