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.
