All of our dimmers are made for LED lighting specificallyour TRIAC leading-edge dimmers are designed to smoothly dim low-voltage LEDs as well as incandescent and halogen bulbs up to 250W. However, like we addressed above, leading edge dimming has welcomed advances in research and technology that have cut these issues out anyways. So, when the voltage fluctuates, the LED bulbs tend to glow more or get dim depending on whether the voltage is high or low. The proportion of dimmable LED luminaires is slightly smaller. The cause is usually a fault in the electronics. Leading edge dimming (also referred to as forward phase-cut, incandescent or TRIAC dimming) is the most common dimming method. If your lights dim when you turn on your air conditioner, clothes dryer, or microwave, you most likely have a circuit problem on hand.
