Generally speaking, the average height of an adult is about 1.6 meters to 1.8 meters, and the sensing height of the motion sensor stair lights is usually set between 1.8 meters and 2.2 meters, which can ensure that the sensor is exactly in the sensing area when a person walks.

The length of the track is generally between 60 cm and 2 meters. Longer track lights can also be spliced ​​to reach the required length. The standard track lights on the market are mostly 1 meter or 1.5 meters long, which is suitable for installation in regular homes and commercial spaces.

Surface-mounted LED downlights usually refer to the lamp itself being exposed and installed on the surface of the ceiling or wall. Unlike surface-mounted LED downlights, recessed LED downlights are designed to embed the lamp as a whole into the ceiling or wall, with only the light-emitting surface of the lamp exposed and the outer shell partially hidden inside the ceiling or wall.

Pros of motion sensor night light: 1. Energy saving and environmental protection 2. Improved safety 3. Convenient operation 4. Extended lamp life Cons of motion sensor night light: 1. Susceptible to environmental factors 2. Installation and adjustment problems 3. Mistakenly turning on or off lights 4. High initial cost

Lumen (abbreviated as lm) is a unit used in the International System of Units (SI) to measure the luminous brightness of a light source. In short, the lumen value represents the total amount of visible light emitted by a light source per unit time.

When people need to get up at night, 1W to 2W LED night lights can provide enough light without affecting sleep quality. These low-wattage LED night lights not only help avoid strong light stimulation, but also reduce disturbance to other family members through soft lighting.

Medium sensitivity is suitable for most common home environments and can detect ordinary people's activities, such as walking and walking. This sensitivity is suitable for most users and can ensure the normal opening of the motion sensor night light without false triggering.

Compared with traditional incandescent lamps, the power consumption of LED wall lights is much lower. For example, a traditional incandescent lamp may require 60 watts of power to provide the same brightness, while an LED wall light only requires 10 watts or less.

Many LED motion sensor night lights have dimming functions or different working modes, and users can adjust them according to actual needs. For example: ● Automatic mode (Auto) ● Constant light mode (ON) ● Off mode (OFF) Switch different working modes according to needs to achieve a balance between energy saving and use effect.

For wardrobes, 5000K LED lamps are not "too bright", but a choice with higher brightness and clarity. It can provide users with accurate color reproduction and efficient lighting effects, especially suitable for places where clothes need to be selected quickly and details need to be clearly displayed.

The light intensity of a wall sconce is usually lower than that of a ceiling light or other central lamp, so when choosing a wall sconce as a vanity light, it is important to ensure that it is bright enough.

When sunlight shines into the room during the day, the temperature rises and the intensity of the light is also strong. At this time, the working environment of the PIR sensor may become unstable, causing the sensor to be unable to correctly judge whether there is human activity.
