  When they were really dim and far too red like 80 years ago? Or when they switched to LED and actually lasted a decade, like now?

  Batteries that last a decade will open up the opportunity for expensive tech like we never imagined.

    Don’t know about you, but LEDs with Edison screws on them don’t last that long. Maybe Siemens or some other brand name manufacturer, but the cheap Chinese ones last only a few months.

    It’s the heat buildup that’s the problem. Disassemble them, slap a CPU heatsink on it and yes, they will last forever.

      Seems like a manufacturer problem. I’ve have the same LED bulbs in my house for 5 years plus with no replacements. Various makes too .Some of them came with me from my old house. No idea how old they are. With incandescent bulbs, I used to have to replace at least 1 a year. I used to keep a stock in the back of a cupboard.

      You’re saying the cheapest possible products don’t last long, while the more expensive ones last for years? Can’t be.

      I’m at 5 years with 12 that are on about 16 hours a day…

        Make, model and price please.

      The problem with led bulbs is that they are build to operate at their limits. It’s still within spec, but just barely which is why they break so quickly. If you would reduce the current by half they would last for decades.

      But of course Big-Light doesn’t want that, so after the initial well-build led bulbs became standard they switched to cheaper designs with less internal led modules for the same brightness.

        As I said, the simplest solution - better cooling.

    Here’s what I was referring to with the lightbulb thing and capitalism:

      Here’s the summary for the wikipedia article you mentioned in your comment:

      The Phoebus cartel was an international cartel that controlled the manufacture and sale of incandescent light bulbs in much of Europe and North America between 1925–1939. The cartel took over market territories and lowered the useful life of such bulbs. Corporations based in Europe and the United States, including Osram, General Electric, Associated Electrical Industries, and Philips, incorporated the cartel on January 15, 1925 in Geneva, as Phœbus S.A. Compagnie Industrielle pour le Développement de l’Éclairage (French for “Phoebus plc Industrial Company for the Development of Lighting”). Although the group had intended the cartel to last for thirty years (1925 to 1955), it ceased operations in 1939 with the outbreak of World War II. Following its dissolution, light bulbs continued to be sold at the 1,000-hour life standardized by the cartel.

  The original Edison bulb still works iirc

  The battery is not the point of failure in contemporary phones, this new radioactive battery doesn’t change much
