Motion sensing light bulbs

Motion sensing lights are a rapidly evolving product. Nowadays the motion sensors are built right into the LED light bulb itself; no clunky hardware or switches. The same sensors in the bulb detect night, so the bulbs only turn on in the dark with motion of a body. They can be used in any socket, and can be placed outside with a little protection. I’ve been trying out the various Chinese-made versions. This one by Luxon costs about $9 and works well enough in our garage, hallway and porch. — KK
