Delay Switch Sensor Lamp Base Sound Voice Control Light Socket Adapter for Corridor Stairs

It only works in the dark. It connects from normal sounds. Pretty good

I don't understand at all how it works, either in complete darkness or that you have to put your finger there for it to turn on. You put your hand there and it turns on, but for some reason it doesn't react to sounds... There is a timer, it lights for about 40 seconds, then turns off. In general, you have to put your hand close to it for it to turn on, I don't know how it will work in the dark.

There are 2 sensors inside - a microphone and a photocell. In a sufficiently lit room, the device does not respond to sound. In low light, a clap of the hand or a command given by the commander's voice turns on the lamp. The burning time is not adjustable and is approximately 30-40 seconds.

I ordered three sets. Connected to electricity. And he clapped and whistled, no matter what he tried, they didn’t want to light up, much less turn off! There are no instructions. Everything on the box is in Chinese. I am not satisfied with the product at all. It's a pity. Please return the money.
