Is this satire, or am I missing something?

It does seem that the filament bulbs check a lot of boxes. The driver is so small it fits in the socket itself. If they can put 1600 lumens in an enclosed fixture, it does suggest they do better with heat. My impression from buying a box is that these are a next generation bulb design, not quite holy grail but a significant step. No more buying bulbs where the bottom half the globe is plastic housing a bunch of driver electronics.

I believe they are referring to LED filament bulbs, which are designed to look like traditional filaments but have the benefit of separating the LEDs from the electronics. More here: https://en.wikipedia.org/wiki/LED_filament https://en.wikipedia.org/wiki/LED_filament

???? I'm not sure what you find to be satire? Have you used these LED filament bulbs? They are very good, the quality of the light is much better than the older style LED bulbs.

  Without some kind of driver, the light flickers strongly at 120Hz. For sensitive people, the effect is extremely unpleasant. One can get perfectly nice drivers and perfectly nice LEDs for less than $25 all in. Sure, many people prefer paying less for a screw-base lamp, but the result is not as good.

    LED filament bulbs do indeed use a driver circuit. Some use a voltage above mains [1] while others drive the LED chain around mains voltage but in a smoother regulated way [2]. Sometimes there's just a basic dropper cap circuit, though. Those flicker but not too badly. The LED design in these is different than in a discrete LED, with the phosphor being quite thick and having a distinct slow fade/afterglow when switched off. I think in this case they basically use the phosphor to smooth out flickering instead of electronics.

  I assume GP interpreted "filament bulb" as "incandescent filament bulb."
