Almost certainly not, but listen:
Crappy fluorescent fixtures flicker at 120 Hz (i.e., 120 times each second, twice the frequency of the AC mains)—but that’s when performing perfectly. Usually, you won’t notice that at all. In fact, a flicker can get down to around 60 Hz before the average person can see it (I’ve been told that this was part of the motivation for choosing that frequency, as early incandescent bulbs would tend to noticeably pulse along with the AC).
But if the fluorescent light is visible and unambiguously flickering, then it’s definitely down below 50 Hz. And here’s the thing: the bright LEDs they’re using in this experiment to successfully treat and reverse symptoms of Alzheimer’s, they’re pulsing at 40 Hz—i.e., the “creepy horror-film industrial building” frequency.
(Please do listen to the entire podcast before deciding to spend a lot of time sitting under shitty office lights; the research is in its infancy and the rate of successful transfer of Alzheimer’s research from rodents to humans is something like 0.4%).
