LED Longevity: The Flash Technology LED L864 beacon uses the LUXEON LED manufactured by Lumileds. Lumileds (HP) started a revolution in LED lighting when they began producing the LUXEON LEDs in the mid-1990s. These LEDs have a number of improvements over the 5mm-type which dramatically extend their life and lumen maintenance. The LUXEONs have a mean-time to failure of about 100 million hours (http://www.lumileds.com/pdfs/RD25.pdf). These LEDs are the most reliable in the world and are used by Flash Technology with the highest quality materials including metal core circuit boards from the most established and experienced supplier. They are used in millions of applications around the world (traffic and obstruction lights) and have never seen a light failure due to an LED. LED Light Output Reduction Over Time: All LEDs exhibit a gradual reduction in light output over time. The reduction in light output depends on the amount of drive current and the temperature of the LED. In the case of the FLASH products, the LEDs are driven at, or even lower than the maximum rated drive current and operating temperature. According to the test data provided by the LED manufacturer, a 25% reduction in light output will be reached at about 40,000 hours. This corresponds to 13.7 to 18.3 years when operated 12 hours per day at 1/2 to 2/3 of the flash period as specified in FAA AC NO.: 150/5345-43F.
