This is impressive. I saw it a week or so ago (the article that is, not the light bulb) and am just getting around to posting. :)
A light bulb in Texas is still burning after it was turned on 96 years ago! It’s not the record holder though. Light bulb still burning after 96 years!
I don’t really know a whole lot about light bulbs, but I would guess it’s possible to make them last that long when one that old is still going. Then again, those companies wouldn’t last very long with light bulbs that worked that well. 100 years from now when our light bulbs went out there would be no one around to make any more! :-P
