That planned obsolescence thing on light bulbs isn't the entire story. Light bulbs will last longer if driven less hard, due to the lower temperature. But that lower temperature also means much lower efficiency because the blackbody spectrum shifts even further into the infrared. So some compromise had to be picked between having a reasonable amount of light and a reasonable life span.

But yeah agree, this subscription thing is spreading like a cancer.

I'm not an expert on the case law, but supposedly United States v. General Electric Co. et al., 82 F.Supp. 753 (D.N.J. 1949) indicates that whatever design trade-offs might have existed, corporate policy makers were really just trying to screw consumers [1] (which is why they probably had to agree on short lifespans as a cartel rather than just market "this line of bulbs for these preferences" vs. "this other line for other people" -- either as a group or separate vendors). I keep waiting for the other shoe to drop where they figure out how to make LED bulbs crappy enough to need replacement.

EDIT: and, shucks, @kragen beat me to it! :-)

Leds are already awful. I already lost 4 of 10 led light bulbs I boughtast year. I hope they will be replaced. It's because every led bulb has a small transformer inside and it fails quite quickly

[pkaye]

I think its a heat dissipation issue. I have some overhead LED lights that replaced some halogen bulbs and they have huge metal heat sinks on the back and have all lasted 10+ years. Unfortunately they are no longer sold but I did buy a few spare just in case.

It depends a lot on the bulbs. When we moved into our current house 11 years ago, we replaced everything with LEDs. Many of those original bulbs are still going strong, including all of the 20 or so integrated pot lights we put in to replace the old-school halogen ones. Others died within a year, and replacements have been similarly hit and miss. To some extent you get what you pay for; most of the random-Chinese-brand LEDs I've picked up off of Amazon have failed pretty quickly. Most of the Philips and similarly expensive ones have lasted. Also the incandescent-looking ones that stuff all the electronics into the base of the bulb tend to fail quickly, as do anything installed in an enclosed overhead light fixture, due to heat buildup.

> as do anything installed in an enclosed overhead light fixture, due to heat buildup

This is my problem. My house has a lot of enclosed overhead light fixtures, and LEDs just do not last long in them. And renovating all of them to be more LED friendly would be quite expensive.

[AndrewDavis]

Interesting, that's been the opposite of my experience.

My Mum converted her homes down lights to LEDs over a decade ago. Hasn't lost a single one.

I moved into my current house 5 years ago, haven't lost a single one either.

I think the quality ranges a lot.

I got one of these free energy audit things which included swapping out up to 30 or so bulbs with LEDs. Whatever contractor did it seems to have gotten the cheapest bulbs they could, and the majority of them have failed by 4 or 5 years later. So far so good on the name brand ones I replaced them with.

[tenuousemphasis]

I think the solution is something like this.

Yes, but the compromise didn't have to be an industrywide conspiracy with penalties for manufacturing light bulbs that were too long-lasting and inefficient. But it was. Consumers could have freely chosen short-lived high-efficiency bulbs or long-lived low-efficiency ones.

In fact, they could have chosen the latter just by wiring two lightbulb sockets in series, or in later years putting one on a dimmer.

"That planned obsolescence thing on light bulbs isn't the entire story."

Whilst that's certainly true the Phoebus cartel's most negative aspect was that it was a secret organisation, its second was that it was actually a cartel. These disadvantaged both light bulb consumers and any company that wasn't a member of the cartel—a new startup company that wasn't aware of or a member of the cartel would be forced out of business by the cartel's secret unfair competition.

Without the cartel manufacturers could have competed by offering a range of bulbs based on longevity versus life depending on consumers' needs. For example, offering a full brightness/1000h type for normal use and a 70% brightness/2000h one for say in applications where bulbs were awkward to replace (such product differences could even be promoted in advertising).

Nowadays, planned obsolescence is at the heart and core of much manufacturing and manufacturers are more secretive than ever about the techniques they've adopted to achieve their idea of the ideal service lives of their products—lives that optimize profits. This is now a very sophisticated business and takes into account many factors including ensuring their competition's products do not gain a reputation for having a longer service life or better repairability than their own (still a likely corrupting factor that originally drove the formation of the Phoebus cartel).

Right, the philosophy's not changed since Phoebus but the sophistication of its implementation has increased almost beyond recognition. There's not space to detail this adequately here except to say I've some excellent examples from the manufacture of whitegoods and how production has changed over recent decades to manufacturers' advantage often to the detriment of consumers.

In short, planned obsolescence and the secrecy that surrounds it has negative and very significant consequences for both consumers and the environment. When purchasing, consumers are thus unable to make informed decisions about whether to trade off the reduced initial costs of products with a short service live against those that have increased longevity and or improved repairability. Similarly, shortlived products only add to environmental pollution, witness the enormous e-waste problem that currently exists.

As manufacturers won't willingly give up panned obsolescence or secrecy that surrounds it, one solution would be to tax products with artificially shortened service lives. In the absence of manufacturing information governments could statistically determine product tax rates based on observable service lives.

They will also last longer if the metal filament is thicker. Which is the way they artificially limited the lifespan.

[tempestn]

But if the filament is thicker you need much more current to get the same level of light, hence much lower efficiency, like your parent comment said.

[bluGill]

That changes the resistance and thus efficiency
