Night Light

Is a night light-activated motion consume less energy than a night which is always on?
You may think that the motion detection light at night is better because it's out most of the time. But for motion detection, would it need a circuit and a chip or something? and therefore, it should convert to AC, so we must constantly consume energy. Right? Considering always-on bulb is not always the AC conversion. It's just. Let the power of 4 watts bulb. Which consumes less energy?
the motion detector only consume energy, but as much power as inside wiring lighting itself (the resistance of the motion sensor is equal to the wiring resistance wire the lights - it draws only a few micro amps). the draw is the real power of the bulb.
