Why do some LEDs blink when dimmed or off?

This is usually due to incompatibility between the driver and the control system. When purchasing LED products, it is important to use the correct driver type specified by the manufacturer. It is also important to check if the LED is dimmable. Some retrofits are not. Our company's Led lighting is made of high-quality LED wicks. At the same time, after the product is assembled, it will undergo a strict stroboscopic test to ensure that the lamp will not flicker under any circumstances.
