The good thing about using motion light bulb is when I come home to a dark room the light will automatically on, it especially benefits is when both hands are occupied with shopping bags. In addition, when kids at home love to turn on light and do not turn it off. Lastly, it is cheaper and easier to replace one light bulb than to replace a motion sensor switch. Since this is a LED light bulb, even if I have to leave the light switch on during the day, I will not waste energy. The bulb looks esthetics just like a normal light bulb. Good thing that I try it.
