At first glance they are fine. But then you see the flickering effect at an AC frequency of 60Hz. That's not a defect, it's the very cheap LED driver inside. If you move your hand quickly, you'll see it frame by frame. This effect can be quite annoying for many people, leading to headaches and eyestrain. So if you spend a lot of time indoors where you plan to install them, I DO NOT RECOMMEND them. Use more expensive and higher quality alternatives.
