LED lighting downlight refers to a cylindrical embedded lamp that uses LED light source as lighting. It is generally installed on the ceiling or other blank positions where light source is required, and the light is irradiated downward through the outer shell of the lamp.

For example, if the area of ​​the walk-in closet is 6 square meters, the total lumen value required is: ● 6 square meters × 250 lumens (lumens per square meter) = 1500 lumens ● For an 8 square meter closet, the total lumen value required is: 8 square meters × 250 lumens = 2000 lumens If the area of ​​the closet is larger, LED light bulbs with stronger light sources or more lamps may be considered to provide sufficient lighting.

For a 30 watt led light, 30 watts of power means that the luminous flux it can produce varies depending on the light efficiency of the LED. Generally speaking, the light efficiency of modern LED lamps can reach 90 lumens per watt or even higher, which means that the brightness of a 30 watt led light can be between about 2700 lumens and 3000 lumens.

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.

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.
