> LED lights are meant to save energy. Spoiler alert: They do. They save up to 90% energy, and quality LED lighting can last much longer. Incorrectly installed LED lights cause light pollution, which is not so much an LED problem, as it is a fixture-design-and-installation problem.

No one cares about pollution though. We can't even get people to care about physical trash. Idk how you would get people to think about light (or sound)

Ah that mythical "quality LED lighting". Anecdotally I saw the switch from normal bulbs to LEDs in my life and the lights break for me about as often. (One light broke in past month, still too lazy to buy a replacement.) So how much more do I need to pay for 90% more efficient LED light that delivers on its "works forever" promise compared to a regular bulb? Also doesn't have flicker? By the way, how dirty is its manufacturing compared to regular bulb?

  Anecdotally, I mostly purchase Philips Hue, and one has yet to fail. Yeah, they are not cheap, but I’ve some of the lamps for many years and they are still doing fine. They have certainly outlasted incandescent bulbs, and at a fraction of the electricity consumption. High quality LEDs are widely proven to be a sound investment. A EUR 2 LED bulb may not fall into the “High Quality LED” group. All of this is widely researched and peer reviewed. The overall ecological impact of using LED bulbs is significantly improved over incandescent or fluorescent lamps.

    Why is it ecologically better in manufacturing? A regular bulb is tungsten & glass, and LED is what? Unlike regular bulbs it's hard to find out manufacturing details for LED, but they usually seem plasticky (= oil and all that) and I guess a lot depends on the kind of phosphorus used etc.

      > Why is it ecologically better? The significant reduction in energy use as well as the long lifespan of the lamps more than makes up for the metals used in the manufacture of the lamps. If this genuinely interests you there is plenty of research available from reputable sources.

        > The significant reduction in energy use as well as the long lifespan of the lamps I meant manufacturing. Longevity we already discussed. LED lamps die on me on the regular and I am not buying a Hue, I need a dumb bulb with a single dim warm color without flicker that's all. > If this genuinely interests you there is plenty of research available from reputable sources. I could not find a good summary on LED manufacturing after cursory search, if you don't really know yourself then it's okay to admit it (but maybe don't claim they're ecologically better without knowing the impact of their manufacturing).

That’s cherrypicking, and also leads me to believe you are not genuinely interested in having and informed debate. > I am not buying a Hue for that money. > I could not find a good summary on LED manufacturing after cursory search. I have, you must not have been looking hard enough. I don’t know what to tell you, buddy. Enjoy your high electricity bills, or alternatively your life with expensive, flickering, poor quality LED bulbs, I guess. I don’t really see this discussion going anywhere for either of us, so good luck with it all.

  I've bought 6 RGB Led lights in 2015 and I have yet to change them. I use them all over my home on the daily with no issues, meanwhile I used to replace 1-2 incandescent bulbs per year at least.

    Honest question: why buy so many RGB lights? Is it for parties? Or it's just impossible to buy a good quality non-RGB light anymore because vendors/retailers push thick margin products? I only use dim warm lights and dirt cheap regular bulbs work great. They last pretty long in that scenario (depends on the unit but that's also true for LEDs) and consume less energy too.

      Sorry for the late reply: I bought LIFX lights because I wanted to have (almost) every bulb in the home remote controlled. I spent more than I had to because high lumens RGB lights are more expensive then white-hot lights. LIFX lights are 1100 lumens, and I had to put 2 for every 1 non-LED bulb I had to produce the same amount of light.
      - throwaway290 3y ago
        OK, remote control is a use case. I am thinking of setting it up a different way to keep using regular bulbs but hadn't gotten around to it yet, home is small enough. I like dim lights indoors after dark so lumens are not an issue.

    Same here. I think I bought my first LED light around 2008, and I think it's still working. I have had some cheap LED lights overheat in fixtures that clearly weren't suitable for them, but when used properly, LED lights can last for a very long time. Incandescents break constantly. Fluorescents occasionally. LEDs almost never, except in very specific cases. If you do have a LED light break within a decade, my advice is to replace the fixture. Or maybe try a very different type of LED (a weaker one with different heat management) in it.
