LEDs are great but they don't last as long as companies say they will. What I have found over the years is the LEDs themselves will last forever. However, it is the power supplies that will die. I will show you what I have found on a motion flood light. A 15 cent fix. Although it costs more at Amazon because of quantity.
Sometimes LEDs blink due to Non Dimmable LEDs being installed in dimmer circuits. Don't do that!
