"Unfortunately, they didn't list the manufacturer or model. If the 
manufacturer is selling 120v models in US big-box stores, I would get a 
couple of them to see if they are radiating about Part 15 limits."

I've listed several in this forum over the years, as I've come across 
them, including several models of the type described.

So far, anything sold as "LED Filament" is going to be the worst noise 
producing POS you've ever heard, and, almost every place that sells 
bulbs are filled with them, having gotten worse in the past several 
years as the stylized bulbs have become more popular.

Anyone else find "led filament" funny?  It's one, or the other, and the 
technologies are unrelated, despite being nearly equally old...

Interestingly, the article does not show the type of bulb described.
