"only heat pumps can be more efficient"

Exactly. And if you have a whole house/apartment electric heating system it is very likely that it is in fact heat pump based. So you are better off using that for heat than the lights.

If your whole house/apartment heating system is gas or oil based, that will probably be even cheaper than the heat pump electric version.

Hmm, where? I have never knowingly been in a house with a heat pump in the UK, and lots of cheaper flats have electric radiators and immersion heaters.

Finite fossil fuels... which might not even be "environmentally cheaper" in the long run...
