“About 10 percent of our LED lights fail”
100% of my incandescent light bulbs failed, not counting the ones I replaced with LEDs.
Not my experience. Before incandescent manufacturing moved out of the USA to China, we had good experience with incandescents. I grew up in SF, and back in the 1970s I pulled some bulbs from the family home that were labeled "Marconi-Edison" - most likely pre-dated the 1906 earthquake in our old home and were still functioning, that's over 70 years of use and still working. Like others, recently we stockpiled incandescents during the switch to CFL's (which we hate and don't use). Our experience is that the USA built bulbs last long, but not the ones made in China.
