Incandescent light bulbs may be fading away, killed off slowly by fluorescents and LEDs, but there's one old-fashioned bulb that refuses to go out. In fact, it's been going for more than a century.
The world's longest-burning light bulb has been shining since 1901, when it was first turned on in Livermore, Calif.

Although this article is almost five years old, Wikipedia says that this bulb is still burning.
“Unfortunately, this bulb type was made for only a year. So dont bother searching for one at your local hardware store”
If they hadn’t stopped making these the lightbulb indusrty would have died adout 99 years ago.
“Something nonpolitical for a Sunday.”
Nonpolitical? That light bulb is a monument to male patriarchy and white supremacy as well as a benchmark in the industrial revolution that caused climate change which has a disproportionate impact on transgendered people and vegans.
Last year I bought some LEDs guaranteed to last 13 years. They lasted just as long as a 100 watt Incandescent but cost 10 times more than the Incandescent bulbs.
it started at 60 watts and has since faded to 4 watts.
I miss incandescent bulbs, primarily because I don’t have to treat a burned-out incandescent as hazardous waste.
Don’t forget that the very idea of an on/off switch is an offence against the non-binary.

I heard about it in high school...late 70s.
Ha! Youre right. That nasty ol light bulb has contributed to Global Warming for 118 years now. Some liberal PhD should apply for a grant to study how this bulb has affected glaciers and polar bears.
Pretty sure the reason that this one has lasted so long is that it isn’t switched off and on very often, if at all.
Gee, and I thought that our two 33 year old functioning light bulbs were pretty amazing. One of them has been used almost every day during this time and they have survived several moves.
*The handle had only been replaced 12 times and the head twice over the decades.
That, and the filament looks quite sturdy. There was a bulb hanging at the old Shakespeare Club building in my hometown that was nearly 100 years old and still working. It was claimed it was made by Edison himself (or his lab staff) but that may be wishful thinking.
The stronger the vacuum the longer the bulb will last. Light bulbs are designed to burn out after a certain amount of time. They could easily make them last 10-20 years.
I actually did buy some 10-year incandescent bulbs, back when they were being shoved out of our lives. They are rated to burn continuously for those 10 years, roughly 82,000 hours, far longer than typical incandescents. The way they achieved that was to burn cooler and dimmer for the same wattage - thus they were even less efficient. But for some locations, where changing the bulb is a really big deal, like in a nuclear plant, where a shutdown might be required to reach it, the bulbs made perfect sense.
