To warm the entire refrigerator box with a 40W bulb is wasteful and will
warm the contents a bit.

Who mentioned 40 watts? A bulb in the box would not change the box temp.

If it does not change the box temperature, it is not going to make the
thermostat do its thing.

The box temp change would be minimal.

... 40 watts burning adds heat

Who mentioned 40 watts?
