"The Phoebus cartel existed to control the manufacture and sale of incandescent light bulbs. " "The cartel lowered operational costs and worked to standardize the life expectancy of light bulbs at 1,000 hours[6] (down from 2,500 hours),[6] and raised prices without fear of competition. The cartel tested their bulbs and fined manufacturers for bulbs that lasted more than 1,000 hours. A 1929 table listed the amount of Swiss francs paid that depended on the exceeding hours of lifetime.[8]" https://en.wikipedia.org/w/index.php?title=Phoebus_cartel&oldid=980971162 https://en.wikipedia.org/w/index.php?title=Phoebus_cartel&ol...
