The Eternal Glow: Why Your Lightbulbs Don’t Last Forever (But One Has for 120 Years)

Here is the true story behind "infinite" light, the engineering trade-offs we make, and the conspiracy that changed the industry forever. The Mystery of the 120-Year-Old Bulb The Eternal Glow: Why Your Lightbulbs Don’t Last

In 1924, major manufacturers (including Osram, Philips, and GE) formed the . They realized that if bulbs lasted too long, they would run out of customers. The cartel standardized the lifespan of a lightbulb to 1,000 hours , even though 2,500 hours was the technical standard at the time. Members were even fined if their bulbs lasted too long. This was one of the world's first major examples of planned obsolescence . The Modern Alternative: LEDs the engineering trade-offs we make
