My LED light bulb won’t turn off completely when I turn off the switch. There is a permanent afterglow or a ghost. What can I do?

Your light bulb is experiencing afterglow when it won’t turn off completely and stays lit, even after you turn off the power switch. Since you are describing a permanent condition, you likely have a switch or dimmer that was connected incorrectly, or unfavorable cable routing, or circuitry that is too old to properly regulate the electrical current. The result is that the LED bulb is operating on lower power than what is normally flowing in the circuit.

Did you recently convert to LED light bulbs from traditional bulbs? Often this issue is only visible when a change to LED is made, though the circuitry issue was still present. Traditional bulbs include a filament that would not be able to light up with leaking currents or induced voltages, while your LED bulb uses less wattage and can glow weakly on low voltage currents.

Please confirm you are using a compatible dimmer switch. We also recommend you consult with a certified electrician in your area to investigate any other issues that might cause this.
