I don't know why they Tweeted about the GermFalcon. Dimer LLC who makes the Germfalcon does not even use LED lights in their products. So besides the confirmation from the company. The non use of LEDs are another type of confirmation they are not worling with Dimer LLc on the IWand
The news that just recently released by OPTI explicitly said UVC LED kills a wide range of viruses with no mention of COVID. The article that was linked in Twitter today says “UV-C Light: It kills COVID and it’s being used in Canada”
My guess is that they linked it to show that Canada is using the same type UVC product to kill the COVID virus.
