People think that govt developed = bad. It’s a consideration for sure but if anything govt developed is so hopelessly and inherently compromised then many of the measures discussed here are useless for privacy already because they almost all run through internet, a govt created system. Even TOR. But yet here we are anyway because they are still useful systems.
Governments pour tons of time money and effort into secure communication, and not for profit, and we can still take advantage of that advancement with some caution.
The bulbs themselves are amazing. There are good ones in cars and computers, the flash of phones etc.
The failure point is typically the electronic components that run or regulate it. And of course most companies want to sell more bulbs so they conveniently skimp on that stuff. So maybe the answer is a more expensive bulb that hopefully will last long enough to justify the extra cost?
