The world's longest-lasting lightbulb has been burning continuously since 1901.
Centennial Light.
They found it not burning in 2013 and thought it finally expired, but it was actually its power supply failing. The lightbulb outlived its wiring.
And if it made you want to know why your brand new lightbulbs burn out in months while this one lasted a century, look up "Phoebus" - the cartel of lighting manufacturers like Philips and GE who purposefully decided in 1924 to limit the lightbulb lifespan to 1000 hours in order to increase sales. That is not a conspiracy theory but a very real historical event.
