They're more expensive to manufacture. They basically triple the number of LED "filaments" you'd find in a similarly-rated bulb, allowing them to run everything well below "max" spec, reducing heat (increasing longevity) and allowing the LEDs to operate at a much more efficient point (less lumens per individual LED, but drastically lower consumption).
- gruez 6y ago>They basically triple the number of LED "filaments" you'd find in a similarly-rated bulb Does it last 3x longer?
- scotty79 6y agoMight last even longer because driving leds at 1/3 of the current might extend their lives more than 3 times (or less but unlikely).
- emilecantin 6y agoYes, but it's not a linear relationship. The gain in longevity is via thermal gains, which reduces the likelihood of component failure. It might be 3x, it might be 10x. You'd get the same (longevity) gains from taking a "regular" LED bulb and running it at lower power. You'd get less light output, though.
- minitoar 6y agoNominally yes, but they also use more expensive control circuitry.
