The story behind such light bulbs is that a cartel of light bulb manufacturers had developed a way for light bulbs to last almost indefinitely. But they realised that if they manufactured light bulbs that last forever, no one would need to buy light bulbs any more. So they standardised light bulb manufacturers’ bulbs to last only 1,000 hours.
This began planned obsolescence in the global economy — the same reason why our mobile phones last about 2 years, laptops last about 4 years.
The result is increased consumerism, increased waste, and is the reason why freeganism can exist.
Then again, if you’re a freegan, you also never need to buy light bulbs again.
