High-quality LED lamp beads can provide stable light output and avoid problems such as uneven color temperature or inconsistent brightness. Consumers should choose LED lamp beads with high light efficiency and long life to ensure the stability of their lighting effects.

The human activity range is an important basis for determining the installation height. Generally, the sensor night light needs to capture the movement of a person's legs, waist or arms. Therefore, the most common installation height is between 0.3 meters and 1.5 meters from the ground.

If the circuit board or driver chip inside the LED lamp is exposed to the outside and is affected by moisture, dust or other contaminants, it may cause short circuit or damage to the electrical components. Failure of the driver circuit may cause excessive or unstable current, thus burning out the LED light source.
