feit

Made by Feit Electric - don't buy that brand.) So if your CFLs are slow buy better ones.

Costco Feit WiFi dimmers can be flashed with esphome with some work, have a few dozen running.

Except for those from Feit Electric - those are terrible, don't buy from that company.

Same with some Feit A19s from a few years back.

I have a number of Feit bulbs which are in their second decade so I don't think it's as simple as a particular vendor skimping.

Of course, that's better than when Feit Electric sent out a firmware update that deliberately bricked all of its smart bulb controller boxes with nothing more than an e-mail telling people it was done.

It took something like 6 years[0] to formalize the proof of Feit-Thomson, one of the first "long" proofs in group theory, and that was done by experts who understood both Coq and the proof.

First verified (= you only have to trust coq small kernel) proofs of four color theorem and Feit–Thompson theorem is enough for real-world?

Feit are the only LED bulbs that I have had straight up die on me inside of a year.

I see something similar offered by Feit, but not quite as elegant.
