LEDs have a projected lifespan of 50,000+ hours, which supersedes most traditional lighting options available in the market today. This robust feature makes LEDs a top choice for residential homes and industrial facilities.
The lifespan of LEDs is affected my numerous factors, from design to environment. Below takes a closer look such factors.
Heat and LEDs
Heat is a leading cause for the deterioration of LED lighting systems. Because of this, a heat sink is typically installed with the unit to ensure proper cooling. Such components could be made out of ceramic or incorporate a passive cooling mechanism (for instance, horizontal fins). These features are effective when the LED fixture is positioned properly.
Incorrect mounting applications may amplify the accumulation of heat around LEDs. For example, a recessed LED lamp mounted on a low ceiling in a garage may cause the light to degrade at a faster rate, without proper protection. A solution to this issue would be to utilize an open mounting setup to allow air flow around the luminary.
When calculating the general lifespan of LED lights, it is important to take lumen maintenance into consideration. This term refers to the output of the LED lamp after a certain period of time. For instance, an LED lamp with an L50 rating refers to 50 percent of output after the unit’s intended lifespan. An L70 lumen maintenance rating provides 70 percent of output after the LED lamp’s estimated lifespan. Lumen maintenance ratings of LEDs are specifically useful for outdoor LEDs and for lighting systems with emergency applications.
Furthermore, high lumen maintenance ratings are ideal for parts of the home where detailed tasks are conducted, which can ensure optimized illumination before the light completely fails. LED fixtures in general locations do not need high lumen retention due to the presence of other lighting systems in the area.
