Description
n 1924, the biggest light bulb makers in the world agreed to limit bulb life to 1,000 hours. Factories sent samples to a lab in Switzerland, and a bulb that lasted too long meant a fine. One company wrote that after shortening its bulbs, sales jumped fivefold. Meanwhile, a bulb in a California firehouse has been burning since 1901.
