Call For Pricing - 800 • 685 • 5267 Medium Intensity Red LED Beacon Obstruction Lighting - FTB 361 - Flash TechL864 LED Photometric Reliability
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.
