Incandescent technology is still superior to any other lighting tech, especially solid state. When one factors in laser sintering of incandescent filaments that increases their efficacy to 3-5 times even LED's, incandescents absolutely rule when considering their performance and cost of production/recycling/logistics/..ect... I love bandgap technology, but it will be hard pressed to beat Edison's brilliance (it hasn't been done yet, despite articles such as this one).
It means nothing. LED lighting is still an infant technology. Any shortcomings are a moving target given how fast the technology is progressing.
The reference to filament sintering is incorrect. First, it's not sintering, it's a process applied to a filament after is has been drawn. Second, the efficiency gain is around double, which still can't even come close to LEDs. Look here for a bit more:
The reference to "production/recycling/logistics" is also wrong if it refers to the EROI of LED lighting, which has already bettered that of incandescent lighting:
