If it is battery-powered, try to replace the new battery and make sure the positive and negative poles of the battery are installed correctly. If it is a rechargeable lamp, try to charge it for 2-3 hours and test it again to check whether the charging port is loose.

● Check the power socket or switch: If it is a plug-in infrared induction led light, try to change the socket or use a multimeter to test whether the socket is powered normally. ● Check the wire contact: For LED lights powered by DC (such as battery power), check whether the battery is exhausted or whether the contact is poor.

it can be seen that not every room needs to install wireless motion sensor led light. For spaces with frequent activities and stable light requirements, such as living rooms and kitchens, traditional lighting systems are sufficient to meet the needs.

The expected service life of incandescent lamps is usually around 1,000 hours, while that of fluorescent lamps is about 8,000 hours. The service life of LED wireless induction lamps is generally between 25,000 and 50,000 hours, and some high-quality products can even reach 100,000 hours.

Traditional LED lamps usually need to be connected to the power supply through wires, while wireless induction lamps rely on batteries or built-in rechargeable batteries for power supply, and use infrared or ultrasonic sensing technology to sense the movement of human bodies or objects.

Night lights usually need to be turned on for a long time, and the long life characteristics of LED lamps make them very suitable for this purpose. The life of LED night lights can usually reach more than 25,000 hours, compared with the much shorter life of traditional bulbs.

If the heat dissipation design of LED lamps is poor, the high temperature of LED chips will accelerate their aging. High temperature will cause electron migration inside the chip, which will reduce its luminous efficiency and eventually lead to brightness decay.

When choosing LED lighting fixtures, consumers should focus on lumens rather than watts. Lumens more directly reflect the brightness of the lamp, while watts are mainly used to reflect the energy consumption of the lamp. Understanding the difference between the two can help consumers make more appropriate purchasing decisions.

According to the principles of physics, the greater the current, the more times the electrons and holes in the LED recombine, and the more light energy is generated, so the LED will appear brighter. For standard LED bulbs or LED panel lights, the relationship between brightness and current is usually linear - that is, the current increases, the brightness increases.

If the lamp uses LED lamps with strong ultraviolet emission, or white and blue LED lamps, it may attract more insects, especially at night or in summer. On the contrary, if the lamp uses red light or warm white light, such lamps will be less attractive and the probability of insects gathering is relatively low.

Generally speaking, the length of the vanity wall light is recommended to be no more than 1/3 of the dressing table. Specifically, for a 72-inch dressing table, a wall light with a length between 24 and 36 inches (about 61 to 91 cm) can be selected.

For example, if you need to provide uniform lighting for a 20 square meter area and the target illumination is 300 lumens/square meter, the total lumens required is: Total lumens = target illumination × space area = 300 × 20 = 6000 lumens Then, calculate the required wattage based on the luminous efficacy of the selected LED lamp. For example, assuming that the selected luminous efficacy is 150lm/W, the required wattage is: Required wattage = 6000/150 = 40W
