I took flickering light from one socket and replaced it with another led it worked fine . LED flicker used to be a common problem. When purchasing LED bulbs and dimmers, it is important to perform a mockup. When converting from halogen bulbs to LED bulbs, there is a decrease in power draw since LED bulbs generally require less power to function. First, check to see if you have loose ground wires. And make sure your LED dimmers are not overloaded. There are one or two possible reasons why your LED lights flickering when you dim them. As a general rule of thumb LED downlights most commonly use constant current drivers and LED strips constant voltage. Now, carefully watch the video you just recorded. The power supplied at your wall socket fluctuates from time to time. Whether you need bespoke brightness-levels or a specific Kelvin rating for your colour temperature, it’s no problem. …the single most frequent cause of visible flicker is the implementation of a dimming function! Always drive LED products using an LED power supply that’s designed for the job. With the number of LEDs in the market, it is easy to buy unproven products. All models with a power output of 100-WATTS, or higher are IP66 rated, which means they can be used outdoors. For example on the LED driver you will see something printed like ‘Output: 350mA’. These old incandescents typically wasted around 90 percent of input energy through heat! This will have an output given as either Amps (A) or Milliamps (mA). We didn’t used to notice it with our old incandescent bulbs, because the bulb’s residual heat kept the filament glowing between flickers. It does this by adjusting the output current accordingly. Three things you can do to stop LED light bulbs from flashing or flickering. The normal cycling of an LED light can cause flickering that is often visible. For example on the LED driver you will see something printed like ‘Output: 12V’. 100 flickers per sec is obviously much better than 50 flickers per sec. In many cases you cannot use a standard wall plate dimmer to dim LED lights. But if all lights flicker, why do some people think flickering LEDs are a problem?
