It just seems like a solution looking for a problem... incandescent lights are exactly the perfect solution for my use case, I am completely happy with them.
The whole problem LED bulb mandates are trying to solve is mostly a problem of unnecessary and excessive lighting which is causing tons of light pollution, interrupting peoples circadian rhythm, etc. If people used a very dim light near their body just between sunset and sleep it wouldn't matter much how efficient it is.
Brightly lighting up our cities and houses is totally unnecessary and terrible for us, and terrible for the planet regardless of how efficient and cheap we can make it. It lowers quality of life for us, and other animals affected by the light pollution.
I would have no problem affording LED lights I don't want, but cannot afford to move someplace with enough land to escape the neighbors light pollution from their cheap LEDs... which makes it harder to sleep, impossible to enjoy the stars, etc.
