Yes and no!
Were talking filament lamps here only. Edison had nothing to do with fluorescents or LEDs.
The longest lasting Edison light bulbs are very dim. Like a lot of things, it comes down to economics. When you buy a filament lamp you are interested in lumens x hours. Lumens is a measurement of the lamps brightness. Furthermore you want high luminous efficiency, that is lumens/watt, since the electric company sells you watts.
So YES some of Edison's early lamps are still working, but that doesn't mean they were good. You can buy an Edison filament lamp on Ebay and screw it into a socket today. Very dim, bubela.
1878
Sir Joseph Wilson Swan was the first person to invent a practical and longer-lasting electic lightbulb.
