The ridiculously dramatic drop in power we dedicate to lighting is one that is just tough for folks to internalize. As you said, used to, you could have ~10 lights in your house that would add to upwards of 1kw. Nowadays, you can have 50 lights and barely hit 500w. Just mind blowing how far we dropped energy on those.
Same goes for televisions. Your modern TV is probably closer to the basic light bulbs before LEDs.
I'm assuming the general trend is true for all things solid state. That said, lighting is by far the biggest drop for most houses. Remarkably so.

For commercial and industrial installations, VFDs have probably been the biggest efficiency gain, even moreso than lighting. Half of all electricity consumed is used by motors. Thank goodness for solid state power electronics!
