With the accumulation of use time and the erosion of sun and rain, outdoor LED linear lights will feel that LED linear lights are not as bright as before after a certain period of time. This has a professional term in the lighting industry - light decay. The physical phenomenon of light decay is an unavoidable problem for LED lamps. Just like life, old and sick, lamps also have a service life.

In the outdoor environment, the daily sun, wind, rain and rain are the inevitable factors that cause the brightness of the LED line lights to decrease. In addition to this unavoidable conditional factor, there are also human factors. Generally, the service life of LED is about 50,000 hours. To understand with ordinary people's thinking, a total of 50,000 hours of life. If the light is turned on at 6 in the evening until 12 in the morning, the light is only turned on for 6 hours a day, one year. 365 days, only 2190 hours in a year, that is not a time that can be used for 23 years.

However, this is only theoretical data in the laboratory. In actual use, the service life of LED line lights cannot be calculated by mathematical multiplication and division. Incorrect use will speed up the light decay time. In addition, in the process of installation, the installers often hope to save installation time and facilitate installation. When the lamps are powered, they are not installed according to the number of LED line lights known by the manufacturer, often overloading the number of series connected lamps, resulting in LED line lights. Behaviors that seriously damage the life of LED strip lights, such as unstable voltage and current. According to market feedback information, it can be known that the service life of outdoor LED line lights will be mostly 2-3 years, and some can reach five or six years, but the longer the time, the lower the brightness of LED line lights.
