Hi US people, european here.

The EU forbid terribly inefficient light around a decade ago. Yes, we had plenty of debates. Yes, people were concerned about all kinds of things. Most of them were entirely made up, some were exaggerated out of proportion.

I can say that we still have lights, the debate mostly vanished and no, it's not blue everywhere.

As we continue to shift our primary motivation for creating products away from what is best for the consumer towards what is best for an artificially determined goal we will increasingly see the compounding secondary effects of those choices.

The "artificially determined goal" here is not roasting ourselves alive in 50 years, which I for one think is a better goal than "satisfying consumer preferences."

let's also not forget maximizing shareholder value, if only for a brief beautiful moment.

This is just an anecdote, but I’ve had multiple “10 year” LED bulbs fail after just a year or two. I suspect much of the claims for these bulbs are theoretical as they just don’t hold up, probably for reasons the grandparent poster is pointing out.

I have too. I have significantly more in my 11-year-old renovation that are still working. That's just the way statistics work. A lot of this topic smells like typical geek snobbery. They're lights, folks. Cheap consumer products have always been cheap. Halogen bulbs suck too.

People have a terrible tendency as well to blame the bulb when it's just overheating in a really bad fixture.

Cost optimization IS the limits of the technology. All the nice things you mention are the result of large amounts of work by exceptional people. This costs money. Most of them require higher-spec components, or more design time, or more complicated fabrication and assembly. These things also cost money. Nobody's denying you nice things at low prices just out of spite. Nice things just cost more. To put a positive sp…

Are there companies out there creating premium LED bulbs without these problems?

Yes. Philips has and Waveform have pretty decent midrange bulbs. Ketra has really, really high quality stuff.

Non-dimmable bulbs are the author's problem. First, bans on incandescent bulbs are foolish because they encourage defeatist foolishness like this article (as far as I can tell, for the sake of virtue signaling and modest acceleration of a change that was already happening.) The CFLs which preceded LEDs were really awful, especially for closets (where they'll linger for decades, given the low utilization of those bulb…

> Non-dimmable LEDs are right up there with running toilets and rodents in the pantheon of things to make homeowners lose their minds. Really? I've never understood the affection for dimming lights. Essentially always I want lights on or off.

I have a lot of dimmers in my house because they were there. It's nice to turn the hall lights down at night when I'm the last one awake (but not if they get too flickery; older dimmers built for incandescent don't always work with dimmable leds), and very nice when watching or starting a movie, etc.

But, dimmable bulbs are also an indicator of quality. Someone cared enough to make sure it worked in that situation, so there's evidence that someone was caring during the design.

>If you’re lucky, the LED will have a CRI of 90 or higher EU has banned incandescent lights years ago and the situation for LED buyers is much different here. My local drug store chain (Rossmann in Germany) sells 1000lm E27 bulbs under their own Rubin brand with CRI>97 for 4.99€. No flickering and available as 2700K or 4000K. My Opple Light Master 3 even reads CRI 100. So for me right now, it's just going to the drug…

I read a lot of the other comments here before yours and they all seemed to describe a reality very different from my own experience. Then I saw yours and it suddenly makes sense. I am also in the Europe, most other commenters seem to be from the US.

Here I find it is very easy to find good LED bulbs with the strength and color profile of my choice and I have used LED in all rooms of my house for the last 10+ years without any failing so far.

Almost all LED bulb failures are because the power supply died due to overheating, not the LEDs themselves. I harvest the LEDs out of dead bulbs to use in hobby projects. With Edison-style bulbs, anyway, the orientation they're mounted in makes a huge amount of difference. They're last a lot longer if they're oriented upright (base down) than in any other orientation because it reduces the heat buildup in the power s…

This is the frustrating thing about LEDs that IDK we can change. If there was a "DC" light socket in the house we could have LEDs outlasting owners, and for cheap. Nearly all the expense of LED bulbs is the power supply. Everything else is dirt cheap. A single home DC power supply with ~200W of output could light an entire house, flicker free. What's even more frustrating is I think we could fix it. A national regula…

Would this system need new electrical wiring ?

Non-dimmableness is only one of the problems. For me the biggest problem is that all LEDs are blue, despite of any light-filters. I can not use it in bedroom when I use to read books before sleep and in bathroom when my aestetical needs of seing bare body have been not met. I have even changed my place of living since Sodium lamps have been replaced with LEDs on my old street. And if I need a really bright light or r…

For reading in the bedroom I use RGB strip behind furniture, preset to yellow. Diffuse light, no blue at all. Of course poor color rendering but I don't mind for this use case.

I came across this article on HN recently: https://www.sevarg.net/2023/02/11/how-your-leds-are-killing-... https://news.ycombinator.com/item?id=34902429 After reading it, I realized that having overhead led lights in our home were possibly contributing to my worsening sleep and general tiredness over the past few years.

I've set up Kelvin[1] to lower the colour temperature of my LED bulbs in the evening, and reduce their brightness. In fact, they end up pretty deep red when doing middle of the night bathroom runs. [1] https://github.com/stefanwichmann/kelvin

Interesting, thanks for sharing. I don't have any home automation stuff, but good to know this exists.

You had this realization and yet still went the route of switching back to all incandescents?

It's trivially-easy to find 2700K LED bulbs. The ones I have look just as good as the old incandescent. And despite the article making it sound like you need a PhD to sort it out, you don't: most medium-end 60W-equivalent, 2700K LED bulbs look good and are easily available in any hardware store.
