I went all LED, finished turn over 2 + years ago. Then I heard horror stories about LEDs and noise. Well in my case I have run experiments without a single light on and with every light in the house on. I cannot see anything. I don’t have a spectrum analyzer but post Covid would treat a tester to a good single malt to see what one would say.
I also highly recommend replacing old fluorescent lights with led strips. They are instant and brighter and trouble free in humid environments like my garage.
