although it certainly is true these days, that the average LED based bulb is pushing those LEDs hard, which incidentally also makes them less efficient, rather than just using more of them at the same wattage. Check out the dubai lamp to see a lamp designed to be efficient and last: https://www.youtube.com/watch?v=klaJqofCsu4 https://www.youtube.com/watch?v=klaJqofCsu4

The Dubai Lamp is not that special. There are similar lamps with only slightly more wattage, but also slightly more lumen. Osram Professional LED Retrofit Classic, or somesuch for instance. In Europe. Don't know about the Americas, Asia...

  I googled that model, it doesn't really seem to have all that many filaments for its wattage rating, so I doubt it's underdriving those LEDs like the dubai lamp. The special thing about it isn't the lumen/wattage, but the longevity by reducing the amount of stress on the LEDs

    When this made the rounds first a while ago, I wondered what the fuss was about and compared. At that time I had only the 'candles' with E14 socket, non-dimmable, clear, at 2.5W, 230V/50Hz: [1] https://www.osram.com/ecat/PARATHOM%20Retrofit%20CLASSIC%20B-Professional%20LED%20lamps%20with%20filament-style%20LED%20technology-LED%20lamps-Lamps-Digital%20Systems/com/en/GPS01_1504753/ZMP_3234835/ https://www.osram.com/ecat/PARATHOM%20Retrofit%20CLASSIC%20B... which seemed comparable, though running at about double wattage. Anyway, they last and last, and I'm perfectly happy with their light. Meanwhile I upgraded everything else also, and have a few of these [2] https://www.osram.com/ecat/PARATHOM%20Retrofit%20CLASSIC%20A-Professional%20LED%20lamps%20with%20filament-style%20LED%20technology-LED%20lamps-Lamps-Digital%20Systems/com/en/GPS01_1504264/ https://www.osram.com/ecat/PARATHOM%20Retrofit%20CLASSIC%20A... also non-dimmable and clear, for lamps with a single E24 socket, which should be bright, at 7.5W & 10.0W, 230V/50Hz. Still very happy with the light, but can't say much about lasting, because only about 2 to 3 years in use, while the candles are now 5 to 6 years old. All 2700k btw. I like it that way. edit: I should add, before that I followed the fad with the CFL stuff, none of which lasted longer than 6 months, made ugly light, and that not even instantly(warm up), sometimes with noisy chirping. So for me it looks like I should have skipped the CFL phase until these were available.

      To be honest I wouldn't want to light living spaces with CRI 80 LEDs, no matter how long they last or how efficient they are.

        Yah, Yah. I hear that so often. Maybe I'm colorblind, and you are all tetrachromates, but I don't see any color-misrepresentations here. And I've tested that.
