I'm well aware of the Phoebus Cartel. It's not as straightforward as often reported. Have a look at Technology Connections: https://youtu.be/zb7Bs98KmnY

Dubai isn't a country. It's a city in the United Arab Emirates.

The Dubai bulb isn't some trick Big Lightbulb doesn't want you to know about, it's an engineering tradeoff: lower current on more filaments gives you higher efficiency and lower temperature but at higher cost and with substantially lower light quality (CRI).

You'll find that after EU energy labeling, there are products available to European consumers that well exceed the specifications of the "Dubai" bulbs. Look for EU energy class A. They often come with a 5-year warranty and rated lifespan of 50000 hours. The "Dubai" bulbs were rated for 25000 hours. You'll also find though that they're substantially more expensive and usually don't have a CRI above 90.

Regarding planned obsolescence, in many cases I can believe that a product will fail earlier than it would if designed for longevity. Rather than planned obsolescence, I believe this is simply a result of being cheap, a consequence of the race to the bottom. If you're buying cheap Chinese fixtures for $10, or cheap Chinese bulbs for $2, you're not going to get a high-quality, long-lasting product.

If you want products that last a long time, buy them and use them properly. If you want bright lights, make sure they're adequately cooled. Consider buying lower-voltage fixtures and bulbs so that you can have a separate power supply and don't put the full ~230V to ~3V conversion in a tiny space.

> Dubai isn't a country. It's a city in the United Arab Emirates.

I learned recently that Dubai is also the name of the emirate. I don’t have a good understanding of the UAE governmental structure, but the Emirates do seem to have their own governments. Maybe it can be thought of as a country in the same way Scotland can be thought of as a country.

Biggest problem of leds is we have no good standards. Classic screw in bulb makes no sense with LEDs. Other formats usually mean you are screwed when you have to replace. So far LED strips seem the best way. A bit of soldering but you can replace them by parts.

Screw in bulbs make plenty of sense. You are not going to get people to convert to LEDs by forcing them to replace every single fixture in their home. That would be ridiculousmaxxing.

		It would be nice to have an updated standard for newer buildings, though. In practice fewer and fewer fittings are using screw-in lightbulbs at all but there's not another standard.

I would love to buy an LED bulb that lasts a long time. I thought the reason for their premium price was supposed long lifetime. Mine all last as long as the older bulbs but cost 5X as much. Where can I buy such bulbs in the US?

There can be a lot of variation. From what I've seen, I'd say 2-5 years is a typical lifespan for an LED bulb. We have some recessed lights in the kitchen that require brighter bulbs, and those typically last only 1-2 years. But then we also have some other (non-replaceable!) recessed lights that are 14 years old and still work fine.

There was one time I bought some cheap ones from Amazon, and several of them failed within a few months. There was also an LED bulb in the front porch light (so, outside) that lasted around 10 years, despite being outside and used daily. I had several of that same type and that particular one lasted longer than all of the others, where the others were all inside and not installed upside down. So yeah, it varies.

		My Philips Hue bulbs are going strong for just over 7 years now. They are the premium bulb in my experience. I've bought other LED strips using controllers compatible with Hue, but they died where there are obvious burned points all along the strip. We all have different experiences that will counter each other, so it's frustrating to no end on finding trust worthy devices. Regardless of all of that frustration, thank the gods we no longer have to deal with CFL
