I looked up one of your links.  It's not the LED bulb that is doing the spying.  It's built into the lamp fixture.  Airports and public facilities have been installing cameras and microphones all over the place.  There are cases when a LED light can spy by covertly listening and then send that audio over 300 meters away to the eavesdropper. But this time, it is the LED fixtures that are the “backbone” of a new surveillance system scrutinizing and recording us. The New York Times reported that 171 LED fixtures inside Terminal B at Newark Liberty International Airport are “watching” us.  I have news for you, there are cameras everywhere.  Your smart TV has a camera on the front.  Your phone has one, probably 2.  Your LED bulb has no cameras built into it.  And unless you connect your lighting to the internet, you won't be pinging the bulbs.  They have to have an IP address to be "pinged". If you are worried about the light fixtures, then you should give your phone more thought.  It "listens" 24/7.  Hey Google, Hey Siri - what's the weather like?
