phones, and light bulbs and an actual conspiracy

that made them worse.

more about them at the end of the video

I am outside Livermore Fire Station, number six.

And in here, they have the longest,

continuously on light bulb in the world.

It has been on for 120 years

since 1901.

There it is.

- [Host] Yeah, that's it.

- It's not even connected to a light switch

but it does have a backup battery and generator.

So the big question is,

how has this light bulb lasted so long?

It was manufactured by hand not long

after commercial light bulbs were first invented,

And yet, it has been running for over a million hours,

way longer than any light bulb today is meant to last.

Awhile back, a friend of mine told me this story,

that someone had invented a light bulb

that would last forever years ago,

but they never sold it

because an everlasting light bulb makes

for a terrible business model.

I mean, you would never have any repeat customers

and eventually you would run out

of people to sell light bulbs to,

I thought this story sounded ridiculous.

If you could make an everlasting light bulb,

then everyone would buy your light bulb

over the competitors.

And so you could charge really high prices,

make a lot of money, even if demand would eventually dry up.

I just couldn't imagine that we had better light bulbs

in the past and then intentionally made them worse,

but it turns out I was wrong.

At least sort of.

Inventing a viable electric light was hard,

I mean, this is the typical incandescent design,

which just involves passing electric current

through a material making it so hot that it glows,

less than 5% of the electrical energy comes out as light.

The other 95% is released as heat.

So these are really heat bulbs,

which give off a little bit of light as a by-product.

The temperature of the filament can get up to 2,800 Kelvin.

That is half as hot as the surface of the sun.

At temperatures like those, most materials melt.

- That's so cool. - And if they don't melt,

they burn,

which is why in the 1840s, Warren De la Rue came

up with the idea of putting the filament in a vacuum bulb,

so there's no oxygen to react with.

By 1879, Thomas Edison had made a bulb

with a cotton thread filament that lasted 14 hours.

Other inventors created bulbs with platinum filaments

or other carbonized materials.

And gradually, the lifespan of bulbs increased.

The filaments changed from carbon to tungsten,

which has a very high melting point.

And by the early 1920s, average bulb lifetimes

were approaching 2,000 hours with some lasting 2,500 hours.

But this is when lifetimes stopped getting longer

and started getting shorter.

In Geneva, Switzerland just before Christmas, 1924,

there was a secret meeting of top executives

from the world's leading light bulb companies,

Phillips, International General Electric,

Tokyo Electric, OSRAM from Germany,

and the UK's Associated Electric among others.

They formed what became known

as the Phoebus Cartel named after Phoebus,

the Greek God of light.

There, all these companies agreed

to work together to help each other

by controlling the world supply of light bulbs.

In the early days of the electrical industry,

there had been lots of different

small light bulb manufacturers,

but by now they had largely been consolidated

into these big corporations,

each dominant in a particular part of the world.

The biggest threat they all faced was

from longer lasting light bulbs.

For example, in 1923, OSRAM sold 63 million light bulbs,

but the following year they sold only 28 million.

Light bulbs were lasting too long, eating into sales.

So all the companies in the cartel agreed

to reduce the lifespan of their bulbs

to 1,000 hours cutting the existing average almost in half.

But how could each company ensure

that the other companies would actually follow the rules

and make shorter lasting light bulb.

After all, it would be in each of their individual interests

to make a better product to outsell the others?

Well, to enforce the 1,000 hour limit,

each of the manufacturers have to send in sample bulbs

from their factories and they were tested on big test stands

like this one.

If a bulb lasted

significantly longer than 1,000 thousand hours,

then the company was fined.

If a bulb lasted longer than 3000 hours,

well the fine was 200 Swiss Francs

for every 1,000 bulbs sold.

And there are records

of these fines being issued to companies.

But how do you make a worst light bulb in the first place?

Well, the same engineers who had previously been tasked

with extending the lifespan now had to find ways

to decrease it.

So they tried different materials,

different shaped filaments, and thinner connections.

And if you look at the data, they were successful.

Ever since the formation of the cartel.

the lifespan of light bulbs steadily decreased.

So that by 1934, the average lifespan was just 1,205 hours.

And just as they had planned, sales increased

for cartel members by 25% in the four years after 1926.

And even though the cost of components came down,

the cartel kept prices virtually unchanged,

so they increased their profit margins.

So did people know that the light bulb companies

were conspiring together to make their products worse?

No, the Phoebus Cartel claimed that its purpose was

to increase standardization and efficiency of light bulbs.

I mean, they did establish this screw thread is standard.

You can find it on virtually all light bulbs

around the world now.

But all evidence points to the cartels being motivated

by profits and increased sales,

not by what was best for consumers.

So one of the reasons this light bulb has lasted so long is

because it was made before the cartel era.

Another reason is because the filament has always been run

at low power, just four or five watts.

It was meant to be a nightlight

for the fire station to provide just enough light

so that firemen wouldn't run into things at night.

And the fact that it was always

on reduced the thermal cycling

of the filament and components limiting the stress caused

by thermal expansion and contraction.

The Phoebus Cartel was initially planned to last

at least until 1955, but it fell apart in the 1930s.

It was already struggling due to outside competition.

And non-compliance amongst some of its members,

but the outbreak of World War II is

really what finished it off.

So this cartel was dead,

but its methods survived to this day.

There are lots of companies out there

that intentionally shortened the lifespan of their products

it's a tactic known now as planned obsolescence.

This was actually the subject of Casey Neistat's

first viral video all the way back in 2003.

- [Support] Thank you for calling Apple, my name is Ryan.

May I have your first name please?

- [Casey] Casey.

- [Support] ] All right, and what seems

to be the issue today?

- [Casey] I have an iPod that I bought about 18 months ago

and the battery is dead on it.

- [Support] 18 months, okay, it's past it year,

which basically means there'll be a charge

of $255 plus a mailing fee to send it to us

to refurbish, to correct it.

But at that price, you might as well go get a new one.

- [Narrator] This video got millions of views

in a time before YouTube or social media.

And it spawned a class action lawsuit,

which Apple settled out of court,

but it didn't stop the company
