Planned Obsolescence is largely a myth, besides a few blatant examples. There are a few factors that drive consumer perception of planned obsolescence

-Demand for cheaper products: Consumers tend to prefer cheaper products. This means cheaper materials and a product that doesn't last as long. Common household appliances cost much less than they did in the earlier half of the 20th century, and people act surprised when they don't last as long as an appliance from the 1950s that cost more than twice as much

-Survivor bias: Only durable products from the past survived, broken and unrepairable products were sent to the landfill. Therefore people only see the most durable products of the past and assume everything made back then was just as durable.

-Technical obsolescence: Old products become less useful as technology progresses. Why use a 100 year old still functional device when it is inefficient and technologically obsolete?

The article even mentions some of these factors with regards to the so-called planned obsolescence of light bulbs. Longer lasting bulbs are dimmer and less efficient, so it makes sense to design them in such a way to maximize light output over a certain timespan.

>Planned Obsolescence is largely a myth

Yes, nobody says "we'll make sure this product breaks in 5 years."

Instead, they say, "We're going to have to support this for 5 years. Design it so that almost all of them survive that long, and don't bother trying to make them last longer. It's too expensive."

In the end, it's the same thing, just without the tint of evil.

Re:The Great Lightbulb Conspiracy by jdietrich on Tuesday March 06, 2018 @09:12AM (#16528942)
If people wanted very durable goods and were willing to pay the necessary cost, they'd be readily available. Most consumers prefer the cheap, semi-disposable option.

A good Makita, Hitachi or DeWalt hammer drill costs anywhere from £500 to £800. It'll provide utterly reliable service over years of daily use and is fully repairable. A store-brand hammer drill costs less than £50, but you'll be lucky if it lasts for more than 10 hours of light use. Most DIYers buy the £50 store-brand drill, because they'll likely only use it a handful of times.

Rapid technological progress makes the semi-disposable option even more attractive. We have the technology to build a laptop that will survive 20 years of heavy use, but who wants to use a 20 year old laptop? Most people get a "free" cellphone upgrade every two years, so what do they care if the non-replaceable battery dies after three years?

Bad for the environment, good for the consumer.

Re:The Great Lightbulb Conspiracy by Doxin on Friday March 09, 2018 @08:06AM (#16551431)
The problem is that I as a consumer have basically no way to tell the quality of products anymore. I could spend thrice as much and still run the risk of getting a product that breaks the second the warranty runs out.
Re:The Great Lightbulb Conspiracy by abakker on Friday March 09, 2018 @02:12PM (#16554070)
Well, you have no free, low-effort way to find out. Reading reviews, looking to consumer reports, demoing things are all options. Of course, they take time and effort. But, really, the backstop is to buy it, use it, and take advantage of generous return policies if things don't work out. I almost exclusively choose my retailers on this basis now.

You can get expensive repairable appliances while last; Miele washing machines, for instance. You'll just pay for them. Most people don't want to pay over a thousand euro for a washing machine, so don't.

Re:The Great Lightbulb Conspiracy by flukus on Tuesday March 06, 2018 @10:39PM (#16534086)
Customers don't have enough information to make an informed decision. I don't mind paying twice as much for something that will last a lot longer, but without a lot of research the price signal is the only indication of quality and more often than not it's just a premium for a well known brand rather than actual quality.

Also, the cost of repair has remained static or increased, while the cost of manufacturing has greatly decreased. Older consumer goods were usually much less reliable than modern equivalents, but it made economic sense to repair them.

In 1984, a 20-inch colour TV cost £329 versus an average weekly wage of £115. In 2017, a 40-inch HDTV costs £300 versus an average weekly wage of £530. TVs are now vastly cheaper relative to the cost of labour.

TV repair used to be very common. There were half a dozen TV repair shops in my town when I was a child. A lot of people preferred to rent, partly because the up-front cost was prohibitive and partly because the rental price included repairs.

Today, even simple repairs like a capacitor replacement are prohibitively expensive. Even if the parts cost pennies and it's a quick replacement, there's a minimum of two hours of labour just to get the back off the TV, find the fault and test the repair. Why pay £150 to fix your old set when you could get a new, better set for £300?

It's not great for the environment, but it's good for the consumer.

  Planned Obsolescence is largely a myth
... aside from the American auto industry up through the 1980s or so. Planned obsolescence drove automotive design for years, prompting people to pursue new vehicles every few years. In contrast, European models could go a decade with little visible change, as long retention cycles were common.

MAD magazine had a great feature in the 1970s called "Planned Obsolescence in Everyday Products", parodying design fails in household appliances and such.

I knew a guy who lived through WWII, he was German. He came to America and bought a 50s Mercedes. When I met him in the late 90s, it had 1,000,000 miles on it. He said he changed the brakes twice and the clutch once.

Over course, I doubted him, but he went into great detail about how he had to drive in post-war Germany, as they couldn't afford replacing anything back then, so everything had to last. He was extremely careful with his down shifting, and only barely touched the breaks at the very end. Accelerated very slowly, etc...

I wonder how much WWII played in Germans making solid stuff still to this day. (and the rest of Europe)

But at least you could buy devices that would last for decades and decades.

Try finding a washing machine these days, that will last for more than 5 years or so before something breaks and renders the machine useless.

You may be able to find an industrial machine, made for hotels or laundries. But it will be very expensive and likely be huge and it will need 3-phase power. It will also likely not have a spin cycle, so you'll have to either air dry your clothes for ages or buy a separate clothes spinner (most driers need the clothes to have been spin dried first).

Whether I buy a cheap Whirlpool or an expensive Miele/AEG/Bosch or whatever, the quality and longevity is universally shit.

Re:The Great Lightbulb Conspiracy by rsynnott on Tuesday March 06, 2018 @07:40AM (#16528424)
> Miele/AEG/Bosch

These aren't comparable; Miele is on a different level. In particular, Miele washing machines are properly repairable. Of course, they're also far more expensive.

EDIT: Missed AEG. These are essentially three tiers of product.

AEG is Electrolux's "premium" branding. In most cases, the same washing machine with different plastic will be available as Electrolux and Zanussi. Very much mid-range; better than Whirlpool/Hotpoint/Indesit, but that's not saying much. Should not be expected to be super-long-lasting.

Bosch (and Siemens, Neff; again, just different branding for the same thing) are definitely a step up. Some though not all machines are very repairable.

And Miele is a huge step up again. All machines should be properly repairable.

Re:The Great Lightbulb Conspiracy by Tomte on Tuesday March 06, 2018 @05:21AM (#16527984)
Only people with broken machines complain. That's why they seem "universally shit".

I've had my Bosch washing machine now for over ten years and there have been no repairs whatsoever, so far.

I'll recycle a comment I made in another thread a year ago:

When clearing out my grandmother's house a few years ago, my uncle and I almost broke our backs trying to get the freezer out. It felt like it weighed a ton, even empty.

My grandmother told us it had been a wedding present, and that they had been totally awestruck at the time at the generous present from her parents-in-law. After all, a decent freezer cost at least 2,000 kroner! (At this time, the average yearly gross pay was just in excess of 7,000 kroner.)

My grandparents married in 1950. Since then, monetary value has been reduced twenty-fold.

You can still buy a top-loading freezer for 2,000 kroner; I just checked.

So - in 1950, you had to work for five months to earn money for a freezer (after taxes.)

In 2017, I have to work one day for a freezer (after taxes.)

Bought my house around 2000 and it had a GE Combination Fridge from the mid 1960's. Looks like this one [1] but in turquoise. Still going 20 years later and all I have done is clean the lint off the cooling fins a few times a year. My Kill-A-Watt says it is about as efficient as a modern fridge.

I think it is just very hard to impossible to judge the quality of an appliance just by looking at it. All external signals a seriously gamed by manufacturers. Even consumer reports does not do a total breakdown by electrical and mechanical engineers to let you know how good something is. Then, at most, 1% of people would care enough to read a quality guide. Price is easy to look at and compare.

Want to by a copper tank water heater that will last a century for your home. Good luck. I've got one from the 50's but I had to know to replace the thermocouple when that breaks once a decade and not just throw it out when it stops working.

Fridges also used to use more efficient coolant, which was outlawed. So newer fridges are typically worse, especially in that they run almost all the time and produce a more annoying sound.

Personally I use an ammonia absorption fridge, the kind of thing you usually only see in hotel minis and camping vans, because of the noise.

Re:The Great Lightbulb Conspiracy by njarboe on Tuesday March 06, 2018 @11:40AM (#16529915)
Do you know of any source for a full size one that could run on natural gas? Like you said, looks like they are all quite a bit smaller (or huge industrial systems). I do dislike the noise of refrigerators and if my current one fails I would like to try a gas powered replacement. Also, natural gas in California is way cheaper per unit of energy than electricity (thanks to Enron and other factors). A gas frig could be cheaper to run than electric here.

What is your point? Are you arguing that the article is exaggerating the role of the international standards body by calling it a cartel? I think one of the main points of the article is that if companies were acting in consumers' interest you'd see the lifespan of bulbs increase while brightness remained relatively steady or also increased (due to advances in bulb tech). As far as light bulbs go, as a consumer, I'd much rather pay more (and do) for a longer lasting bulb in the 27-35k temp range than perpetually need to replace bulbs that burn up at 45k+. If you're arguing consumers prefer brighter shorter bulbs and that that drove the market, you're directly contradicting the article which has plenty of citations and makes a very compelling argument. Care to share yours?

Thomas Pynchon integrated this story into Gravity's Rainbow. There are some amazing passages imagining the fortunes of Byron, a sentient bulb who is determined to escape his own mortality --- the planned obsolescence of Phoebus:

" Is Byron in for a rude awakening! There is already an organization, a human one, known as “Phoebus,” the international light-bulb cartel, headquartered in Switzerland. Run pretty much by International GE, Osram, and Associated Electrical Industries of Britain, which are in turn owned 100%, 29% and 46%, respectively, by the General Electric Company in America. Pheobus fixes the prices and determines the operational lives of all the bulbs in the world, from Brazil to Japan to Holland (although Philips in Holland is the mad dog of the cartel, apt at any time to cut loose and sow disaster throughout the great Combination). Given this state of general repression, there seems noplace for a newborn Baby Bulb to start but at the bottom.

But Phoebus doesn’t know yet that Byron is immortal. He starts out his career at an all-girl opium den in Charlottenburg, almost within sight of the statue of Wernher Siemens, burning up in a sconce, one among many bulbs witness the more languorous forms of Republican decadence. He gets to know all the bulbs in the place, Benito the Bulb over in the next sconce who’s always planning an escape, Bernie down the hall in the toilet, who has all kinds of urolagnia jokes to tell, his mother Brenda in the kitchen who talks of hashish hush puppies, dildos rigged to pump floods of paregoric orgasm to the capillaries of the womb, prayers to Astarte and Lilith, queen of the night, reaches into the true Night of the Other, cold and naked on linoleum floors after days without sleep, the dreams and tears become a natural state… "

While most people forget to mention when discussing the Phoebus cartel is that with incandescent lightbulbs, lifespan and efficiency are inversely correlated.

It is actually quite simple: incandescent lightbulbs are blackbody radiators. Efficiency depends only on the temperature of the filament, the hotter the better, but lifespan decreases drastically as temperature increases.

There isn't much that can be done in an incandescent light bulb. The filament is tungsten, voltage is fixed by the grid, power is the rated power. So, the only choice is to make the filament longer/thinker or shorter/thinner. The former will be dimmer and longer lasting compared to the latter.

Requiring a set lifespan also ensures consistent brightness and color temperature (a real temperature in this case), it also requires reasonably precise manufacturing. These are generally good things.

Well obviously, a lot of it is motivated by profit, but there are also very good technical reasons behind it too.

The situation today with LED lighting is actually much worse. LEDs could last a lifetime, unlike with incandescent light bulbs, there is no reason for them to burn. However, a lot of them fail because they are under-engineered.

Re:The Great Lightbulb Conspiracy by timcederman on Tuesday March 06, 2018 @01:30AM (#16527264)

More than half died within 6 months, another crop in under a year, and I've got two of them that are still running fine 7 years later. They run probably 12 or 15 hours a day every day of the year.
Re:The Great Lightbulb Conspiracy by hazeii on Tuesday March 06, 2018 @09:03AM (#16528883)
Have you compared the brightness against a new LED of the same model? My experience with many higher-power (60-100w equiv.) bulbs is that they are quite a lot dimmer after a year or two of heavy use.
Re:The Great Lightbulb Conspiracy by PeterStuer on Tuesday March 06, 2018 @02:19AM (#16527411)
Slightly OT: In winter, when you are heating the rooms anyway and so any heat produced is useful, not wasted, is an 'old' incandescent light-bulb still significantly less energy efficient then a 'modern' energy saver bulb?
Re:The Great Lightbulb Conspiracy by abainbridge on Tuesday March 06, 2018 @03:03AM (#16527574)
Yes because you could heat the room with gas heating, which is about 3x cheaper. And if you are in an area that uses a lot of gas/coal in the electric generation, then you will significantly reduce greenhouse gas emissions too.

Or you could run a heat pump, that wins about a factor of 5.

I learned this from this excellent resource: https://www.withouthotair.com/

There's an argument that

Re:The Great Lightbulb Conspiracy by PeterStuer on Tuesday March 06, 2018 @03:42AM (#16527679)
So you're saying 'it depends' on the differential in methods for producing electricity versus your other heating sources, which makes sense. If I have a solar roof for the electricity, vs an oil from fracking powered heating solution, then the lightbulb's 'waste' heat would certainly be preferable.

Part of the reason for asking in the first place is because I'm quite sensitive to the light quality as produced by an incandescent bulb, preferring it vastly over even the most 'modern' 'energy saver' bulbs.

Re:The Great Lightbulb Conspiracy by abainbridge on Tuesday March 06, 2018 @04:56AM (#16527903)
Yes. And I think there's some benefit to the planet from incandescent bulbs being a simple and cheap technology to manufacture (although I have no justification for this belief).

Anyhow, I agree about incandescent bulbs being nice. I never found a CFL I was happy with. The Philips LED bulbs are very good though: https://www.amazon.co.uk/Philips-Bayonet-Light-Bulb-Frosted/...

They don't flicker (and I'm someone infuriated by PWM'd lights on modern cars). They achieve full brightness instantly. The colour temperature and spectral rendering index is good. They are much more reliable than some similar unbranded bulbs I've seen (about 15 such bulbs were installed in my kitchen area at work. They fail at a rate of about one per month, in a manor consistent with this https://www.youtube.com/watch?v=94Pemtc3Uhw).

They do cost £9 for two though. They'll need to run for about 500 hours to pay for themselves (vs incandescent). I reckon the first one I bought has run for about 2500 hours by now.

Re:The Great Lightbulb Conspiracy by PhantomGremlin on Tuesday March 06, 2018 @06:52AM (#16528253)
The older Philips LED bulbs were very high quality. Dimmable, no flicker, power factor corrected. Here's a youtube teardown. https://www.youtube.com/watch?v=OWKAub54sLU Compare the internal circuitry with the youtube video you linked to. Yours were a cheaper design. No wonder the bulbs failed so quickly.

Nowadays Philips seem to be selling both a higher quality and a lower quality bulb in each wattage.

To me the purchase price isn't an issue. I have a few places where I run bulbs 15 or 20 hrs a day. So moving from 60 W to 10 W in those locations made an incredible cost savings. Where I am in the USA, a 1 W load on continuously costs $1/yr. So saving 50 W in a location that's on about 80% of the time saves me $40/yr in electricity. For just one bulb.

Re:The Great Lightbulb Conspiracy by dwild on Tuesday March 06, 2018 @10:57AM (#16529581)
I'm pretty sure you don't need to generate more heat in the summer though, so that's still a loss there.

Re:The Great Lightbulb Conspiracy by Terr_ on Tuesday March 06, 2018 @04:07AM (#16527753)
If you can use the electricity that was saved to pump heat then that'll be more efficient.

If the only alternative usage is putting the energy into a different hot metal filament, then it might be more of a tossup, depending on how focused the light-bulb's emanations are onto the things you actually want warmed.

Even disregarding pump vs direct heating and thermostat regulation: Heating from your ceiling is pretty inefficient since hot air tends to ho upwards and straight out the air vents.

What's with the scary hedge at LED dominance?

"Whether or not these pricier bulbs will actually last that long is still an open question, and not one that the average consumer is likely to investigate. There are already reports of CFLs and LED lamps burning out long before their rated lifetimes were reached. "

Other than warmth, my home LEDs (all of them - Cree) have lasted 7 years and look to last about 10-15 more. They've already paid for themselves as before that I was replacing 4-5 bulbs a year and wasting 10x the wattage.

Re:The Great Lightbulb Conspiracy by Spooky23 on Monday March 05, 2018 @09:14PM (#16526362)
Many LED bulbs have performance issues, especially in fixtures.

There’s such a large market now it’s hard to identify quality product. Good news is that the prices have fell to the point that the ROI in energy savings is very short.

Re:The Great Lightbulb Conspiracy by wlesieutre on Tuesday March 06, 2018 @12:41AM (#16527102)
There's the Lighting Facts labels so you could at least see a 3rd party validated lumen output and color temperature. If you've seen the labels that look like nutrition facts on LED bulb packaging, those. Also served to track the overall progress of the LED industry.

Re:The Great Lightbulb Conspiracy by digikata on Monday March 05, 2018 @09:54PM (#16526529)
My suspicion, CFL tubes generally had plenty of life. On the other hand CFL power supplies had be be miniaturized and high voltage. Many of my old CFL bulbs had melty spots somewhere. So they generated a lot of internal heat with an inefficent supply.

If the LED bulb needs a power supply, it's much lower voltage (and there are an abundance of component choices for those voltages - at least more so than fluorescent bulbs), and there's been lots of work for efficient power supplies in that range. Also there's new no-power supply LED filament bulbs expanding in the market now, and I would think those would tend to last even longer with much fewer components to fail.

https://en.wikipedia.org/wiki/LED_filament

Re:The Great Lightbulb Conspiracy by aidenn0 on Tuesday March 06, 2018 @12:04AM (#16526987)
Also CFL bulbs were rated for running in an open fixture; the power supplies are somewhat heat-sensitive so putting them in e.g. a can can greatly lower their lifetime.
Re:The Great Lightbulb Conspiracy by tjohns on Monday March 05, 2018 @08:28PM (#16526176)
My Philips Hue LED bulbs have been very reliable.

On the other hand, some cheap no-name chinese LED lamps I got off Amazon started failing after less than a year.

There definitely are some bad, short-life LED bulbs out there -- especially on the lower end of the market.

Re:The Great Lightbulb Conspiracy by Turing_Machine on Monday March 05, 2018 @11:38PM (#16526896)
There's a Philips LED (one of the weird looking three-lobed ones) that has been burning continuously in the entryway of my inlaws' house for over seven years. It's a 60W equivalent. I bought it for them because a) the light burns all the time (even in daylight that area is dark) and b) it's a pain in the butt to change.

I think it was about $45 when I bought it. A similar model is down to $21 for a 100W equivalent now.

I've got several other Philips bulbs of that type that have been in use for a long time, though not quite that long.

I've never had one go out.

As with you, I've had numerous cheapies go out over the same interval.

Re:The Great Lightbulb Conspiracy by wlesieutre on Tuesday March 06, 2018 @12:59AM (#16527168)

Re:The Great Lightbulb Conspiracy by Lazare on Monday March 05, 2018 @08:50PM (#16526276)
Yes. I bought some very cheap LEDs of AliExpresss, but they failed quite quickly (no surprise). Name brand bulbs from my local supermarket have, so far, held up vastly better.

One of the more amusing ways the cheap bulbs failed is by neglecting to use UV stabilisers, so just leaving the bulb on would cause them to degrade their own housing until they fell apart. (The other main failure mode I saw was the transformers giving out.)

Re:The Great Lightbulb Conspiracy by zaarn on Tuesday March 06, 2018 @04:07AM (#16527752)
It depends on the quality a bit.

From my experience, about 1/5th of LED bulbs fail within the first year.

However, all lamps that survived the first year haven't broken in 3 years total yet.

I think it might be related to the internal powersupply, some had visible stress damage from thermal cycles (molten, cracks, etc.).

I also had a few LEDs in an RGBW strip fail that I use for lighting though I soldered around that.

Re:The Great Lightbulb Conspiracy by janesvilleseo on Monday March 05, 2018 @08:15PM (#16526120)
For what it’s worth, I have taken my LED bulbs back to Home Depot and have gotten then replaced at no cost. This is a lot easier with their electronic receipts as I can easy look through my receipts and pull it up to show purchase date.

I suppose this is what happened with CF bulbs? We were promised longer bulb life, but in practice I find that I have to change CF bulbs far more often than traditional fluorescent tubes. It's going to take quite some engineering to develop LEDs that burn out fast enough.

CF bulbs were sold as having long life compared to the incandescent bulbs they were drop-in replacements for, not compared to flourescent tubes.

Re:The Great Lightbulb Conspiracy by Johnny555 on Monday March 05, 2018 @09:43PM (#16526490)
I think a lot of CFL lifetime depends on the quality of your electricity. In my last place, I had some that lasted 8 years including some high-usage lights like in the livingroom that saw at least 3 - 5 hours of daily use.

Though I always purchased name-brand bulbs, never the cheap generic brands.

I left them all behind when I moved so those are the longest lived ones I have experience with, in my new house, I have mostly LED's with a few CFL's and they're up to around 5 years old... I like the light from LED's better or I'd have more CFL's around.

Failures have been rare, but I have pretty clean power, few power outages and practically no thunderstorms in the area.

Re:The Great Lightbulb Conspiracy by jdmichal on Wednesday March 07, 2018 @05:46PM (#16540699)
Interestingly enough, in one apartment I had a particular fixture that would burn out incandescent bulbs extremely quickly. I put in a CFL and never had to replace it again. No idea what was going on there.
Re:The Great Lightbulb Conspiracy by klondike_ on Monday March 05, 2018 @10:20PM (#16526621)
This has to do with the starter mechanism. All florescent tubes need a starter, including CFLs. Industrial/commercial florescent lights take a few seconds to warm up, often with some flickering. For home use people want their light bulbs to start up fast, so manufacturers put quicker starters in CFLs at the expense of longevity.
Re:The Great Lightbulb Conspiracy by blattimwind on Tuesday March 06, 2018 @04:13AM (#16527774)
Your information is out of date by a few decades or so.

Ballast + starter is completely outdated and the only reason you still see them is in places where they don't care about energy costs and because hardware stores still sell them (along all the other junk products found in hardware stores) — they are marginally cheaper.

Combine a fluorescent tube with a hot-start electronic ballast and you get lights that are cheaper than LEDs with similar efficiency and light quality (depending on the tubes), but lower eco-footprint and lower running costs (tubes are ~1-1.5 € each). Electronic ballasts are extremely reliable and have been on the market long enough to back such claims up.

Hot-start EVG doesn't turn on quite as fast as LEDs; they take about 0.5 seconds. They never flicker.

Re:The Great Lightbulb Conspiracy by sevensor on Monday March 05, 2018 @08:45PM (#16526252)
Both. It was in a rented apartment. My best guess is that decades of heat cycling had caused the filament to sag.
Re:The Great Lightbulb Conspiracy by MertsA on Tuesday March 06, 2018 @02:46AM (#16527511)
It probably wasn't sagging that killed it. Over time those elements will develop hot spots and eventually the hot spot fails spectacularly spewing sparks and plasma from the failure. It's kind of similar to a plasma cutter for a second as there's the small arc in the element which ionizes the gas and it blows it out from the element and if it hits something grounded I can totally see it punching a hole through sheet metal.

Re:The Great Lightbulb Conspiracy by stevekemp on Monday March 05, 2018 @11:47PM (#16526923)
I'm from the UK, and I'm all too familiar with the two-types of bulbs.

But a couple of years ago I moved to Finland, and it seems here that the Edison-screw won. I've not seen a single bayonet mount since I've moved here. (And I've moved flat a few times. When you rent a flat they are typically unfurnished, and the Finns take this to an extreme, removing all their light-bulbs along with the furniture.)

Re:The Great Lightbulb Conspiracy by pluma on Tuesday March 06, 2018 @04:32AM (#16527844)
Situation in Germany is pretty similar. I've never seen a bayonet mount in my life, I think. Also our flats don't come with lightbulbs either.

Every German who has moved flats a couple of times thus owns a few barebone lamp socket assemblies which are affectionately called "Russian chandeliers" (with apologies to Russians). When moving in these are usually the first things to go up until proper lamps are installed.

EDIT: I think I've seen bayonet mounts in some antique furniture at my grand parents' house as a child. But it certainly strikes me as a bit of an anachronism, much like American farmhouse style windows (the kind you slide up) compared to tilt turn windows (which are the norm in my country).

Re:The Great Lightbulb Conspiracy by zaarn on Tuesday March 06, 2018 @04:04AM (#16527746)
I've seen the edison/screw mounts in basically any residential setting here in Germany.

Some industrial applications use the bayonet mount, usually when the lamp itself doesn't use standard 230V AC to prevent mixups (IIRC mercury lamps use bayonets for this reason, you don't want it in normal sockets)

Re:The Great Lightbulb Conspiracy by Gibbon1 on Monday March 05, 2018 @08:31PM (#16526189)
Interesting thing I learned was before WWII you could buy cold cathode light fixtures and get the local neon shop to make a lamp for it. Cold cathode lamps will last 20 years.

The light bulb manufacturers got those outlawed via the national electrical code. It's illegal to have any wiring in a residence over 1000. Except for radio's televisions and microwaves. Which means cold cathode lighting is outlawed. Cold cathode is basically just neon, which is similar to fluorescent except unlike fluorescent you don't have a hot filament to burn out. Both requires higher voltage to operate and results somewhat lower efficiency, but with 100,000 hour life span.

Later in the 1970's they also made sure that fluorescent lamps efficiency standards mandated high color temperature (blue) phosphors. In low light residential use high color temp makes everything looks like ass.

Maintaining old software is expensive and people do not want to pay. It is also way easier to just pull everybody with you to latest release (which is why there are so many subscriptions now).

edit: also, I do know a lot of developers that would not be happy to work on the maintenance of some old software.

One can learn from the light bulb conspiracy that planned obsolescence is real. It is profitable unless they are caught for companies to make products with a limited life thus they can sell replacement products and bad for the environment.

Re:The Great Lightbulb Conspiracy by mc32 on Monday March 05, 2018 @11:58PM (#16526959)
Poor economies (think underdeveloped economies) do incentivize repair over replacement. Cases in point, cars in Cuba, Former USSR republics, etc. You will also find repairshops for electronics in many developing economies as well. Labor to repair a unit makes a repair affordable whereas buying a new unit might be prohibitive.

In developed nations, labor is too expensive to make a repair worthwhile for things people can regularly afford. It's only as things become expensive that repairing something makes economic sense (a $100 replacement screen for a phone is economically viable vs buying a new $600 phone). Conversely very few people in the US for example would think of repairing an old Microwave when buying a new one is only marginally more expensive than getting a new one.

Re:The Great Lightbulb Conspiracy by namdnay on Tuesday March 06, 2018 @10:26AM (#16529372)
Indeed, a good example of that is the fact that people export very old used cars from Europe to Africa, because due to the much lower cost of repair their value in Africa is higher than their value in Europe (nil), enough to make it worth the shipping!
Re:The Great Lightbulb Conspiracy by jerf on Tuesday March 06, 2018 @10:45AM (#16529497)
Unless you can find repairpeople willing to work for a great deal less than minimum wage it's going to be hard to make this work on most gear. Labor alone is enough to kill repair efforts. Even if corporations tried to make more repairable gear it wouldn't help if labor is still too expensive to make it worth it. (And if that's true, then making the gear less repairable and cheaper becomes a rational response to the market rather than a conspiracy.)
