The bell at our main entrance has what I'd regard as a fairly normal
bell transformer and I've just metered it at 3W. At the other door is a
battery-operated bell which needs two D cells about every ten years. So
obviously batteries win on cost grounds but I regard the illumination of
the main door bell push, and the reassurance it offers when pressed, to
be worth the small amount I pay.

Err, compare like for like. If you used your illuminated bell push with
the batteries they'd be flat in short order. Similarly that 3W would be
drastically reduced without an illuminated push.
