Light bulbs that last like 50-60 years?

There's a spiral type of bulb in my parents house that has never been changed and it still works. They bought this house 45 years ago and the house was old when they bought it. I'm guessing this bulb has been working for at least 55-60 years

Did you know that the light bulb was the first item that manufactured standardised it's longevity.They all agrees on 1000 hours.A considerable reduction on existing bulbs at that time.To increase sales of course.
