I went and bought one. Before the decision I tried it on the store. At home the flicker was way too visible even with pretty bright settings. I got awful eye pain and headache. I recommend to be careful if you are able to see LED flickering.
QuoteHumans can perceive light oscillation at frequencies slower than 50 hertz, although some people notice it up to 100 hertz, says Nadarajah Narendran, director of research at the Lighting Research Center (LRC) in Troy, N.Y.
Quotemoderate flicker frequencies, from about 100 hertz to as high as 500 hertz, can lead to indirect perception of stroboscopic effects, in which objects in motion can appear as a series of still images. But what may be desirable in a dance club can be dangerous in an industrial setting. For example, flicker can make moving gears or blades look slower or even stationary, and it has been associated with adverse health effects such as headaches, eye strain, and fatigue.
QuoteAs the flicker frequency increases into the kilohertz range, around 2 kilohertz and higher, preliminary research suggests that "we can no longer detect it," says Jim Benya, principal at Davis, Calif.–based Benya Burnett Consultancy.
