Interesting article! I thought the quote I pulled from it below was very telling…
"LEDs bulbs can then transmit data, and “anything with a camera, like our smartphones, tablets, or laptops could be the receiver,” Xiong says. "
Since the climate change thing is a scam… I tend to believe that LED bulbs are being pushed for other reasons.
Personally I don’t use LED bulbs because the lighting sucks… But I think they probably play a role in the control grid that they are trying to roll out. I bought some bulk incandescent bulbs on Ebay 
Yet people still scoff at the idea that recent fax scenes might have been engineered to contain electro-biologics.
“Ultimately,” Xiong says, “we want to be able to harvest waste energy from all sorts of sources in order to power future technology.”
Oh, what a virtuous, high-social-credit-scoring little Borg drone you’ll be if you volunteer to help the planet by donating your own “waste energy”… The sociopathic scientists strike again! Shades of that patent (from Baal Gates’s former company) to use human energy for mining cryptocurrency. Where do they find the twisted minds that come up with this stuff?
