Are you sure? Doesn’t the “smart edison bulb” design make it harder to dissipate heat to the casing, therefore making the LEDs get hotter compared to PCBs with LEDs surface mounted on them?
Anyway, if you want your light bulbsany technology to last long, don’t buy the “smart” variant. “Smart” usually means more components and/or more dependencies on interfaces, and more complexity, so a higher chance to fail.
As far as I understand, the latency is improved by the different speed of light of the DNANF: In conventional fibres, it is limited by the refractive index of glass, reducing the speed of light in it to ~70% of speed of light in vaccum (Wikipedia on this topic). In this new concept, the light travels 45% faster.
I think, the lower loss (lower attenuation) is “just” an enabler for long distances: You can easily have hundreds of km without repeaters – and repeaters for DNANF cables would add latency. If they can get attenuation improved a bit more, they may even be able to cross the Atlantic ocean without repeaters.
As a nice side effect, those DNANF cables have very little dispersion, so you can get rid of compensating for that, which will reduce latency too.
