"Aging profile" is a really good point. Especially since LEDs generally don't burn out, but just get dimmer and dimmer. You might need to remind yourself to replace them someday even if you don't notice a problem.

I had one of the early LED PAR-38 (?) lamps that Costco recalled after they discovered that their lifespan was much shorter than they promised. I didn't return mine and generally forgot about it. When I finally replaced it, I was stunned at how bright the replacement was in comparison! Like the boiling-frog parable, I just didn't notice how dark the room had become because it got dim so slowly.
