I wonder if it’d be worth it to centralize the inverter…

It lasts long because it's not turned off. When an incandescent bulb turns on the filament shakes violently.

It used to be that you only had one option so you didn’t have to think about it. But, that single option was at least "good enough". I never bought a normal incandescent bulb only to have the color rendering/brightness/etc be downright awful. LEDs come packaged as "daylight" or "bright white" or whatever else. I want one that's labelled "just like your normal 60W incandescent".

> But, that single option was at least "good enough". Was it? Or was it what we were all used to, good or not, so we accepted it as good/correct.

Effectively every incandescent bulb has good CRI and can be dimmed, so yes.

My experience is opposite of yours. I have not yet had to change an LED light in the last 8-9 years since I started using them and replacing incandescent ones in my apartment. On the other hand I remember changing incandescent ones quite often and using up all the surplus ones I had after I started the transition to LED.

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 w…

> I am also in the Europe, most other commenters seem to be from the US. You're falling for the "Europe is better than the US, of course" mindset. What you are actually seeing are partisans spinning a narrative to fit their ideology, not an accurate description of reality. We have really high CRI bulbs here, too, and they're inexpensive. I can go down to the home store and buy them by the dozen. I'll bet you money th…

Please link me to a 95+ CRI bulb available at Home Depot or Lowe's.

Who sponsored this terrible article? Should we also go back to 25" console tv's that sit on the floor, with decorative brass handles just so this author can avoid ever having anything be different in their life? I've never, not even once, had an LED bulb misbehave as described in this article. They are at least as reliable as CFLs were, and although there are tradeoffs with other bulb types both good and bad, LEDs consume effectively no power compared to incandescent.

From the article: ``` I’d put one in the bedroom-ceiling fixture only a few months before. In theory, it should have been the last I would put up there for years, maybe even a decade. Instead, the bulb was a dim, dull orange, its levels of brightness visibly fluttering through the frosted dome. ```

What? And then they go on to talk about how hard it is to illegally find incandescent bulbs. This screams cognitive dissonance. An incandescent bulb's normal way of responding after several months to a year was to just not work anymore at all. That was just 'normal' and you would swap them out. If you went to any room in the country and looked at the light fixtures, you had a very good chance of finding bulbs that were burned out. It was normal to hear or say "we really need to replace the bulb in the pantry" but in the meantime not be able to see in there very well. Finding one led bulb that fails early is not an indictment of the technology, even if it was defective. For all we know his kid might have been throwing water balloons at it.

LED bulbs are great, they are now incredibly cheap and there is no reason to keep producing CO2 because of misoneic propaganda. If we want to reduce carbon emissions, we either have to pass the true cost of carbon to consumers, which would mean dramatically increasing energy costs to people who likely can't afford that, or we need to make it less likely to consume all that artificially cheap electricity wastefully. LED bulbs are a great way to do this.

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

Forget about premium, what the hell are impoverished people supposed to do?

Save on their electric bill with cheap LEDs that get the job done, while worrying about more important things than if the bulb flickers sometimes when you dim it?

This is where the idea meets the real world implementation. Yes, LED's can last longer, but the additional electrics used to convert from house-hold AC power can't.

You can go buy high CRI, high quality bulbs right now. Nothing is stopping you. Here is one common vendor: https://store.waveformlighting.com/collections/a19-bulbs/ The issue isn’t that MBAs have cost reduced bulbs for no reason. The issue is that 95% of consumers will only choose the cheap bulbs, period. As a result, that’s what gets produced at scale. > We know how to mass-produce quality LEDs to the point entire T…

As consumers are we really supposed to do a ton of research on light bulbs and accept that we can't run down to Home Depot and get some new bulbs when they go out in our house?

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…

It's about choice. I have several dozen LED can lights in my house producing 1600 lumens each. Sometimes I want every bit of that power, but I also like being able to turn them down a bit in the evening when I don't need it.
