Generally, the service life of a high-quality LED light source is between 30,000 and 50,000 hours, which means that if used for 8 hours a day, the service life of the LED light source is about 10-17 years.

The sensor sensitivity is too high Most LED night light lamps are equipped with sensitive motion sensors to respond quickly to motion in low-light environments. However, if the sensor sensitivity is set too high, it may react to minor environmental changes or non-human movements.

The sensor is blocked or installed in an improper position LED motion sensor night light relies on sensors to detect motion, and if the sensor's sensing area is blocked or the light is installed in an improper position, it will cause the sensing function to fail.

Many modern LED night light lamps have a "constant light mode" option. In this mode, the lamp does not rely on the trigger of the motion sensor, but is kept on all the time directly through the switch or remote control.
