The stroboscopic of downlight will be harmful to vision health, here is a tips to test stroboscopic degree: when you get the LED downlight, you could plug the power and light the lamp, use the camera function of mobile phone to close to the luminous surface, then you can observe whether there is a stroboscopic phenomenon.High quality led downligth must be equipped with good chip and driver .
