Only thing i found is my hallway is not the brightest so the bulb didn’t work but tried it in a lamp by the window and it works fine so it’s got to be my hallway

I don’t understand how this works

Posted by a reviewer on Amazon

The lightbulb has a light sensor on it so when it’s light it’s off and when it’s dark it’s on

But when it switches on because it’s dark it then becomes light so therefore should switch off

What is particularly good is the fact that there are two light sensors on each bulb on opposite sides so that if you for example end up having one positioned against a wall the other side should still get light

Ive personally positions such that one sensor is east and the other is west in order to maximise the amount of time they are off for

Bought it for porch but because it’s recessed does not work as well as it might

They both function very well but would love to know how the inside one knows when to turn on and off when it gets dark and then light from the light itself does not turn it off
