Interesting! Why faulty LED bulbs in particular, does it have to do with their PWM frequency?

- unnouinceput 3y agoBecause their power supply is shitty and it's easy to transform the chopper that is used in the switching power supply to behave as an oscillator instead, which will start to emit harmonics (https://en.wikipedia.org/wiki/Switched-mode_power_supply https://en.wikipedia.org/wiki/Switched-mode_power_supply)
- jacquesm 3y agoElectromagnetic radiation power roughly equivalent to the amount of light they output. I wished I was kidding, some of them are so bad they should qualify as jammers.
