Phoebus Cartel
The Phoebus cartel was a 1924 international agreement among major lightbulb manufacturers to control production, fix prices, and artificially limit bulb lifespan to about 1,000 hours through planned obsolescence. It operated until World War II and later faced legal scrutiny for anti-competitive practices.
Background
- The Phoebus cartel was a 1924 agreement among the world's major lightbulb manufacturers (including Philips, Osram, General Electric, and Tungsram) to fix prices, divide markets, and — crucially — standardize the lifespan of incandescent lightbulbs at around 1,000 hours, even though longer-lasting bulbs (up to 2,500 hours) were technically feasible.
- This is a classic & frequently cited case of "planned obsolescence" — the strategy of deliberately designing a product with a limited useful life so that consumers have to buy replacements sooner, boosting manufacturers' profits.
- The cartel enforced its 1,000-hour standard through fines and testing labs; it was effectively dismantled after WWII amid antitrust actions, especially by the U.S. Department of Justice against GE in the 1940s–50s.
- The Phoebus cartel remains a key reference in debates about sustainability, consumer rights, and whether modern tech companies (e.g. Apple with battery-throttling or smartphone software updates) also build in artificial obsolescence.
