These LED bulbs have a built-in motion detector and automatic detection of day or night, so that this LED will only work in darkness and movement.
When the ambient lighting is less than 10Lux ± 5Lux, the light will switch on if a person will be detected by the motion detector
When the ambient lighting is more than 30Lux (± 5Lux), the lamp will not switch on if a person is detected by the motion detector.
With motion detection, the lamp will remain on for approximately 6 seconds, without the lamp having received a new detection. For example, if the lamp has received a new detection after 3 seconds, the operating time starts to count down again to 6 seconds.
