Motion Night Light

You may think that the motion detection light at night is better because it is off most of the time. But for motion detection, would need a circuit and a chip or somethinga and therefore, it should convert to AC, so it would be necessary to constantly draw power. Righta Considering always-on bulb is not always the AC conversion. It's just.

Let the power of 4 watts bulb. Which consumes less energya

motion detector only consume energy, but as much power as the wiring inside the light itself (the resistance of the motion sensor is equal to the resistance of the cable wiring to the light - it draws only a few micro amps). the draw is the real power of the bulb.

4 Wattsa It's nothing to light. Even then, the motion sensor draws very little.
