The most common cause of flickering LED lights is a poorly matched LED power supply, otherwise known as a LED driver.LED lights either require a constant current LED driver or constant voltage LED driver. Existing dimmer switches often have a minimum power of 50W, but because LED lights tend to have lower wattages than the standard bulb when a bulb is connect to that dimmer switch it will not reach the minimum power required and would usually confuse the dimmer switch and the lights start to flicker, make buzzing noise or overheat. Manufacturers also provide compatibility charts, and it is best practice to evaluate them.
