The Phoebus Cartel: How Light Bulb Manufacturers Colluded to Shorten Product Lifespans

The Problem of Durability

• 💡 Companies face a challenge: making products too good reduces repeat sales and profits.
• 📌 Nearly 100 years ago, industrialists attempted to solve this by intentionally making products worse.

The Phoebus Cartel's Formation

• 🤝 In the early 1920s, light bulb manufacturers like General Electric, AEG, and Philips recognized their products were becoming too durable, lasting 2500+ hours.
• 🌍 To combat declining sales, representatives from major global companies formed Phoebus SA in Geneva in 1924, a cartel to standardize light bulb lifespans.
• 🎯 The primary goal was to standardize incandescent bulbs to a lifespan of 1,000 hours, a significant reduction from existing durable products.

Cartel Operations and Enforcement

• ⚖️ Phoebus SA established a system where member companies submitted bulbs for testing, facing substantial fines for exceeding the 1,000-hour standard.
• 📈 This enforcement mechanism was effective, leading to a dramatic drop in average bulb lifespan by the late 1920s.
• 🌐 Beyond lifespan, the cartel also divided global markets, shared patents, and suppressed innovations that threatened their agreed-upon standards.
• 📊 Phoebus SA controlled approximately 90% of the world's light bulb production, wielding significant influence over the industry.

Decline and Lasting Legacy

• 📉 The cartel's operations faced challenges in the 1930s due to the Great Depression and rising nationalist policies, and effectively ceased with the outbreak of World War II.
• ⏳ Despite the cartel's dissolution, the 1,000-hour standard became deeply embedded in manufacturing practices and consumer expectations, persisting for decades.
• ⚠️ While there was a technical argument for shorter-lived bulbs offering better light quality and efficiency, the necessity of the cartel suggests market forces alone did not drive this standard.

Modern Parallels to Obsolescence

• 📱 Today, companies like smartphone manufacturers face similar challenges, relying on new features rather than planned obsolescence to encourage upgrades.
• 🚗 Automobiles also last significantly longer due to improved technology and materials, with manufacturers focusing on added features and higher prices.
• 🚫 Cartels like Phoebus are rare today due to increased antitrust scrutiny, though exceptions like OPEC exist.
