6. What is the lifetime of a LED Lamp?
When properly installed and well ventilated, LED Lamps will very rarely burn. However, the brightness of the LED light fade over time, so LED Lamp's life is measured by 2 characteristics - how much will it fade after 1,000 hours of exploitation, and when the brightness will reach 70% of the initial value.
Quality LED Lamps are rated at less than 3% light output decrease for the first 1,000 hours, and 30,000 to 50,000 hours for the 70% decrease, which is the standard for commercial lighting applications.
Again, compared to traditional light sources, LED lights are superior regarding lifetime.
