Lack of information can be harmful, and in John's case, it resulted in chronic migraines.
John rapidly replaced the expensive traditional lights in his house with the inexpensive LEDs you can find everywhere after learning that LED bulbs don't flicker. To his dismay, he discovered that LED lights can flicker, which can have a variety of negative effects, such as chronic migraines.
John found our website while experiencing migraines and the flickering problem and sought for help. Simply purchase LEDs that don't flicker was our guidance.
The problem is this. LEDs are not created equally. LEDs come in two varieties: those that flash and those that don't. The majority of the LED lights on our website don't flash.
Which LED light will flicker and which won't? How can I know in advance? You may inquire.

But I don't see any flashing in my LED lights. So why even try, you ask?
LEDs can flicker clearly (as in John's case) or covertly show a stroboscopic effect, which can wear you out, irritate you, and in rare instances, give you migraines.
What is stroboscopic?
While we pledge to keep things as straightforward as possible, it's important that we comprehend what the term "stroboscopic effect" refers to.
The stroboscopic impact is described by PHYSORG as follows:
When a moving object is illuminated by fluctuating light, this effect appears as a sequence of still pictures. This effect is frequently used in discotheques in its most intense version.
Stroboscopic effects from LED lights can be undesirable.
Three factors are important to keep in mind when considering the stroboscopic effect:
Let's assume for the sake of ease that there are only two kinds of stroboscopic light: one that you can see and one that you can't.
However, even visible stroboscopic light is nearly difficult to distinguish if you don't know what to look for.
The non-perceptible variety is something you don't need to worry about because it is not associated with side effects (We assume, it's a case of if you can't see it, you don't need to worry about it). Finally, the perceptible stroboscopic effect is harmful for you because it can result in the side-effects described above.
We want to emphasize that you should always check whether an LED bulb has the "flicker-free" sign before making a purchase because even if your LED doesn't appear to be flickering, you shouldn't assume it isn't because it may be producing a stroboscopic effect that you can't see.
To get to the root of the "your LED bulb may be flickering but you might not be seeing it" conundrum, there is a quick test you can perform.
If you quickly swing a pen up and down in front of an LED light and then quickly do the same while standing in front of a window, you should notice a change. If not, there is no need for concern.
Your LED bulb is producing perceptible stroboscopic effect, which as we've said before can have negative effects, so change these bulbs as soon as possible with non-flickering LED bulbs if you notice a continuous blur when you swing the pen quickly up and down in front of the window but all that's visible in front of your lamp is still images.
Of course, it would be much easier if you just bought the non-flickering LED lights in the first place; that way, you wouldn't have to think about a thing.
