You’ve probably heard the rumors. Somewhere in a dusty basement in California, a light bulb has been burning since 1901. It’s called the Centennial Bulb. It’s a thick-filament hand-blown wonder that just won’t quit, mocking every single LED or incandescent you’ve bought in the last decade. It’s weird, right? We can send rovers to Mars and map the human genome, yet the glass orb in your hallway ceiling seems to pop if you look at it funny. This isn't just bad luck. It's actually one of the most documented cases of industrial sabotage in history. When people talk about the Phoebus cartel, they aren't wearing tinfoil hats; they’re reading business history.
Basically, back in the 1920s, light bulb manufacturers realized they had a massive problem. Their product was too good. If a light bulb lasts forever, you only sell one to a customer once. That’s a terrible business model if you want to keep the lights on—literally—at the factory. So, they did something that changed the global economy forever. They broke the product on purpose.
What Really Happened with the Phoebus Cartel
In December 1924, a group of suit-clad executives met in Geneva. These weren't low-level managers. We’re talking about the heavy hitters from Osram, Philips, Tungsram, and General Electric. They formed what became known as the Phoebus Cartel. On paper, they called it a "standardization" effort. In reality, it was a global conspiracy to control the lifespan of the incandescent lamp.
Before this meeting, bulbs frequently lasted 2,500 hours or more. The cartel decided that was unacceptable. They mandated that every standard household bulb must have a life expectancy of exactly 1,000 hours. Not more. Not much less. Just 1,000.
Think about the sheer engineering effort required to make something worse. Engineers who had spent years trying to increase efficiency and durability were suddenly told to go in reverse. They had to find ways to make filaments more fragile. They had to ensure that the heat of the bulb would eventually cause the internal components to fail at a predictable rate. It’s wild.
If a company got caught making a bulb that lasted 1,500 hours, they were fined. The cartel had a strict system of bureaucracy to track this. They tested bulbs from every member frequently. If your bulb was too durable, you paid a penalty. It was a race to the bottom, managed with the precision of a Swiss watch. This is the origin of planned obsolescence, a term that now defines almost everything we touch, from your smartphone battery to your washing machine.
The Math of Failure
The engineers didn't just guess. They used physics. By increasing the voltage or thinning the filament, you can make a bulb brighter, but you also make it burn out faster. The 1,000-hour limit was the "sweet spot" they found to maximize sales without making consumers so angry they stopped buying bulbs altogether.

By the early 1930s, they had succeeded. The average lifespan of a bulb across the globe plummeted. This wasn't a secret held by two guys in a basement; it was an international agreement involving dozens of companies and thousands of employees. It worked because they controlled the patents. If you wanted to compete, you had to play by their rules.
Why the Light Bulb Conspiracy Still Matters Today
You might think this is ancient history. Who cares about a 1920s business deal, right? Well, the Phoebus Cartel set the blueprint for the modern world. It’s why your iPhone starts lagging exactly two years after you buy it. It's why "fast fashion" exists. We live in a throwaway culture because these guys proved it was more profitable than building things that last.
Market competition is supposed to make products better. That’s the theory. But the Phoebus story shows that when the biggest players in an industry decide to stop competing and start collaborating, the consumer loses every time.
Actually, the cartel didn't fall apart because they felt guilty. It ended because of World War II. When the world went to war, the international trade agreements and patent-sharing deals crumbled. Plus, the lawyers eventually caught up. In 1953, a U.S. court finally ruled that General Electric and its partners had violated the Sherman Antitrust Act. They were ordered to stop the price-fixing and the lifespan-limiting practices.
But here is the kicker: the 1,000-hour standard never really went away. It had become the industry norm. Even without a formal cartel forcing them to do it, manufacturers realized that consumers had been "trained" to expect their bulbs to die. Why go back to making 2,500-hour bulbs when the public is already used to replacing them every year?
The LED Revolution and New Tricks
Fast forward to the 21st century. We have LEDs now. They’re supposed to last 20,000 to 50,000 hours. It's a miracle of technology compared to the old glowing wires. But have you noticed that some "cheap" LEDs seem to flicker or die after just a year or two?
Often, it’s not the LED itself that fails. It’s the "driver"—the little circuit board inside the base of the bulb that converts your home's AC power to the DC power the LED needs. Manufacturers can save pennies by using low-quality capacitors in these drivers. When the capacitor pops because of heat, the whole bulb goes dark, even though the actual light-emitting diodes are perfectly fine. It’s Phoebus all over again, just with silicon instead of tungsten.
Honestly, it’s kinda frustrating. We have the technical capability to make a light bulb that outlasts a human being. We’ve had it for over a century. The Centennial Bulb in Livermore, California, proves it. It's a 4-watt bulb that’s been on since 1901, and it’s still glowing. It’s not bright, and it’s not efficient, but it’s reliable.
The Economic Impact of Forced Waste
Planned obsolescence isn't just about making you buy more stuff. It has massive environmental consequences. Think about the millions of bulbs, phones, and appliances that end up in landfills every year because they were designed with a "death date."
- Waste: Millions of tons of electronic waste annually.
- Energy: The energy required to manufacture replacements is often higher than the energy saved by "more efficient" short-lived models.
- Cost: The "subscription" model of ownership where you never truly own a working device forever.
Some experts, like Giles Slade, author of Made to Break, argue that our entire modern economy is propped up by this cycle of waste. If products lasted 50 years, the GDP would collapse. Or would it? Some brands, like Miele or Patagonia, lean into durability and do just fine. But for the mass market, the ghost of the Phoebus Cartel still haunts the assembly line.
How to Fight Back
You don't have to just accept that things will break. There is a growing "Right to Repair" movement globally that is fighting back against these practices. Countries in the EU are starting to mandate that products must be repairable and that spare parts must be available for years after a product is discontinued.
When you’re looking at the Phoebus cartel and its legacy, the best thing you can do is change how you buy.
First, stop buying the cheapest option. If an LED bulb is $1, ask yourself where they cut corners. Usually, it’s in the heat management or the driver components.
Second, look for certifications. Bulbs with an "Energy Star" rating aren't just about using less power; they have to meet certain longevity standards that the unrated junk doesn't.
Third, support the Right to Repair. Whether it's your phone or your tractor, the ability to fix what you own is the only real way to break the cycle of planned obsolescence.
The story of the light bulb isn't just a conspiracy theory about shadowy men in smoke-filled rooms. It's a very real, very documented business strategy that shaped the 20th century. It taught corporations that they could control the clock on their own products. But as consumers become more aware of these tactics, the power shifts back.

We might not all get bulbs that last 100 years, but we can certainly demand better than 1,000 hours. The next time a bulb in your house flickers out, don't just blame the hardware. Remember the meeting in Geneva. Remember that sometimes, the world is designed to fail so that someone else can keep selling you the solution.
Practical Steps for Longevity
To minimize the impact of modern planned obsolescence in your home lighting and tech, try these specific actions:
- Check the Heat: Heat is the number one killer of electronics. Ensure your LED bulbs have enough ventilation. Putting an LED in a fully enclosed, tight fixture is a death sentence for the driver circuitry.
- Verify Ratings: Look for L70 ratings on lighting. This tells you how long the bulb will last before it loses 30% of its brightness. High-quality industrial bulbs often have significantly better L70 ratings than the ones you find in the "bargain" bin.
- Invest in Modular Tech: When possible, buy devices where the battery or the components can be swapped. This is the direct opposite of what the Phoebus Cartel wanted.
- Demand Transparency: Support legislation that requires companies to disclose the expected lifespan of their products on the packaging.
The Phoebus Cartel won the first round by setting the 1,000-hour standard. But today, with the internet and global awareness, we have the tools to call out these practices. Durability should be a feature, not a fluke.
