Q. What is covered by your warranty?

Answer:The warranty given as standard ensures that the performance of the light meets the required specifications for the entire 5 year period. Please see Warranty for details.

Q. How does one know when an LED product is out of photometric specifications?

Answer:Our warranty allows for a minimum of 5 years of operation while ensuring the beacon meets the FAA"s minimum photometric requirements. LED"s do not "burn out" similar to incandescent. An LED will have a slight degradation of light output with use. This is similar to the degradation of a strobe tube.
