Worlds oldest light bulb is still going strong after 110 years. This is like wow. For a long time it has been on. Still, I do wonder what substance it uses. Most tungsten bulb last 400 hours and that is pushing it. Well, this one keeps on going. It was created by Adolphe Chailet, an inventor and competitor of Thomas Alva Edison - imagine.
