With the accumulation of use time and the erosion of the sun and rain, the LED line lights will feel that the LED line lights are not as bright as before. This has a professional term in the lighting industry-light decay. And the physical phenomenon of light decay is an unavoidable problem for LED lamps. Just like life, disease and death, lamps also have a service life.

In the outdoor environment, daily sun, wind and rain are the inevitable factors that cause the brightness of LED line lights to drop. In addition to the inevitable conditions, there are also human factors. The service life of general LEDs is around 50,000 hours. Use ordinary people's thinking to understand. The total lifespan is 50,000 hours. If the light is turned on at 6 in the evening until 12:00 in the morning, it will only be on for 6 hours every day for one year. 365 days, 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 line lamps can not be calculated by mathematical multiplication and division. Incorrect use will also accelerate the light decay time. There is also that during the installation process, the installer often hopes to save installation time and installation convenience. When the lamps are powered, they are not installed according to the number of LED linear lights connected to the manufacturer. They are often overloaded and connected in series, resulting in LED linear lights. Behaviors that seriously impair the life of LED linear lights, such as voltage and current instability. According to market feedback information, it can be known that the service life of outdoor LED line lights generally is 2-3 years, and some can reach five or six years, but the longer the time, the lower the brightness of the LED line lights.
