My experience has been that they last for more years than I tend to notice which ones are which. I’m not mad at all about their longevity.

I had 2 LED bulbs that I know for sure that I bought prior to 2015 that only recently failed. Those bulbs lasted at least 9-10 years. The rest of my bulbs I haven’t kept up with but those 2 older ones looked very distinctive with aluminum heatsink material for their bottom halves.
