Main wall plug source can be tested by borrowing some UPS (Uninterruptible Power Supply) to deliver current without being plugged in the wall.

No noise with unplugged from wall UPS : Main is the culprit

 

Did you read the one link previously that I provided? Here's two that you'll also probably skip.

Basic fucking physics says that non-ionizing radiation such as UV light is harmful, on a sunny or even a cloudy day it can burn skin...obviously. Are you arguing against yourself?

Don't make your own bias a personal attack.
