Old fluorescent lights have a ballast that can get loose and start to buzz at 60 hz. Other faults can add noise that any good mic can hear, but there are certainly electrical fields vibrating too.
I was surprised to not be bothered by the fluorescent lights when I worked in a sign shop. It turned out that we had to do color matching, so they were full-spectrum tubes. I've used those ever since for most things.
have heard of such a thing ,, little experience with them .
Have heard of such variable spectrum LEDS , yes indeed.
Famous qoute from a movie ' Dont Go into the Light'
