I had an LED porch light that lasted ~10 years. The fixture had light and motion sensors, so it wasn't on during the day or all night, and often it was not running at full brightness, but still it was on a lot. I was surprised it lasted that long, especially since it was outdoors.

I switched to all LED lighting many years ago. I've had a few that lasted less than a year, but by and large I'd say that nearly all the lights I've had have lasted at least on the order of years.
