I spend a lot of time under LED lights and it's very important to me that they don't flicker. This significantly reduces eye fatigue. You might not be able to see the flickering with the naked eye, but if you use your phone and capture slow motion, you'll see it in all its glory, if there is one. White 3000K. There is no flicker at all! I compared them to three other brands that claimed no flicker and they were all terrible. Don't waste your time and take it, you won't be disappointed.
