Average lifespan of COM-12986 Addressable LEDs?
If you want to find the lifetime of an LED ask the manufacturer if its not listed in the datasheet. In the past I've also looked for LED's with simmilar specs to get a ball park estimate. These are usually MTBF ratings. that means some will fail early and some will last a lot longer. Usually part degradation is due to heating so any way to minimize heating will help (either by reducing the power or some other means.) I think 100k hours is what we used for the lifetime on our LEDS in our products so we turned them off when we wern't using them. But have you ever had a VCR or other product with a burned out LED, I never have noticed any, but most of them are low power.
