Here the voltage-carrying conductor can induce a voltage in the conductor separated from the switch. This means that there is a low voltage in the ceiling light even when it is switched off, which causes the LED to light up weakly.

Why is my light bulb still on when switched off?

The filament of an incandescent bulb gets extremely hot to give off white-hot light. When you turn off the power to the bulb, the filament takes a few seconds to start cooling down. So it continues to glow slightly as the filament is still quite hot for a few seconds.

Why does my light stay on dim when I turn it off?

Parallel cables running long distances through corridors or staircases to supply electricity to another point induce some voltages due to electromagnetic induction. These conductors are connected to the switches. The small induced voltages can cause the LED light stays on dim when switch is off.

How do you fix LED ghosting?

3 options here:

  1. Change the LEDs to an approved product- may not solve the problem.
  2. Change dimmer to the PD-6ANS- most likely would solve or at least reduce the “ghosting” you are experiencing.
  3. Try the LUT-MLC- lots of posts on this, Lutron reluctantly has mentioned the MLC with dimming now.

Why are my LED lights ghosting?

What causes LED bulb ghosting? In most cases, when you turn a standard dimmer off, the electronics inside do not receive any power. Caseta wireless digital smart dimmers still need to receive a small amount of power to be able to receive RF signals. This tiny bit of current can cause this bulb ghosting phenomenon.

What is light ghosting?

Ghosting is a faint lighting from residual current in the inserts. Strobing is actually seeing the cycle rate in a GI bulb. You are likely losing sight of the ball from the reflection of the light on the ball, even with frosted bulbs.
