Markus Krajewski reports that today, with many countries phasing out incandescent lighting in favor of more-efficient and pricier LEDs, it’s worth revisiting the history of the Phoebus cartel—not simply as a quirky anecdote from the annals of technology but as a cautionary tale about the strange and unexpected pitfalls that can arise when a new technology vanquishes an old one. Prior to the Phoebus cartel’s formation in 1924, household light bulbs typically burned for a total of 1,500 to 2,500 hours; cartel members agreed to shorten that life span to a standard 1,000 hours. Each factory regularly sent light bulb samples to the cartel’s central laboratory in Switzerland for verification. If any factory submitted bulbs lasting longer or shorter than the regulated life span for its type, the factory was obliged to pay a fine.
Though long gone, the Phoebus cartel still casts a shadow today because it reduced competition in the light bulb industry for almost twenty years, and has been accused of preventing technological advances that would have produced longer-lasting light bulbs. Will history repeat itself as the lighting industry is now going through its most tumultuous period of technological change since the invention of the incandescent bulb. "Consumers are expected to pay more money for bulbs that are up to 10 times as efficient and that are touted to last a fantastically long time—up to 50,000 hours in the case of LED lights. In normal usage, these lamps will last so long that their owners will probably sell the house they’re in before having to change the bulbs," writes Krajewski. "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 are reached. "Such incidents may well have resulted from nothing more sinister than careless manufacturing. But there is no denying that these far more technologically sophisticated products offer tempting opportunities for the inclusion of purposefully engineered life-shortening defects."

I write the install date on the base of the CFC or LED bulb.
I know for a fact CFCs last far less time than they claim.
Its hard to judge how much burn time they have, (and their hours rating is based on hours per day, which seems daft).
But even in low-use places (garage, spare bedrooms, etc) the life is a lie.
LEDs: Jury still out. But they never get hot enough to burn the sharpie off, so you can date them anywhere.
No, you are mistaken. I've always had this sig.

The one that I have that has survived and still works is mounted upside down and burns 24/7. I suppose I could burn all my lights 24/7 but it's still not practical for me to replace every light fixture to match that orientation.

This seems to be the great mystery. I have CFs mounted in various orientations, indoors and out and have few failures even over the stovetop or in the bathroom. Others with seemingly less hostile setups have constant failures. I have no idea what the independent variable is there but it sure would be useful to know.

Well, I have m any that have lasted several years. Longer than incandescents in the same fixtures. But I had a more than a few failures as well. Usually burned out their ballasts. The power savings over their life may not have actually paid for the bulbs. (But I didn't pay for most of them either. The regional power company gave them away, All I had to do was pay the tax. (no clue why that requirement was in place).
I've now witched to those cheap Cree bulbs. It will probably be a few years till I know if they were worth the money. But if you shop those on sale you can be get them for half price. So far, none of those have failed.

I haven't figured it out either, but see above where I mutter about having noticed it's a per-socket thing, regardless of bulb type -- at least so it was in the last two houses I've lived in.
And there is no Alkibiades to come back and save us from ourselves.
