With the accumulation of use time and the erosion of the sun and rain, the LED linear lights will feel that the LED linear lights are not as bright as before after a certain year. This is 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, the lamps and lanterns also have a service life.
In the outdoor environment, the daily sun, wind, and rain are the inevitable factors that cause the brightness of the LED linear lamp to decrease. In addition to this unavoidable conditional factor, there are also human factors. Generally, the service life of LEDs is about 50,000 hours. To understand from ordinary people’s thinking, there are a total of 50,000 hours of life. If the light is turned on at 6 in the evening every day until 12 in the morning, the light is only on for 6 hours a year. 365 days, only 2190 hours a year, isn't that 23 years?
However, this is only theoretical data in the laboratory. In actual use, the service life of LED linear lights cannot be calculated by mathematical multiplication and division. Incorrect use will also speed up the light decay time. In addition, during the installation process, installers often want to save installation time and ease of installation. When the lamps are powered, they are not installed in accordance with the number of LED linear lights known by the manufacturer. Often the number of lights in series is overloaded, resulting in LED linear lights Behaviors that seriously damage the life of the LED linear lamp such as unstable voltage and current. According to market feedback, it can be known that the service life of general outdoor LED linear lights will be 2-3 years, and some can reach five or six years, but the longer the time, the lower the brightness of the LED linear lights.
