LED can lights slightly illuminate when other room is switched on!?

We have 6 LED can lights in the kitchen on a binary switch and 6 LED cans in the living room on a dimmer. When the living room lights are switched fully on and the kitchen switch is off, the kitchen lights faintly illuminate. And as the livingroom lights are dimmed the kitchen lights correspondingly brighten slightly.

Is this maybe related to the dimmer being substandard?

Why are you using a binary switch? Why not a regular light switch?

What a binary switch is. Did you mean duplex switch?

I did not realize ‘binary’ actually was a specific type of switch in this context- I just meant the kitchen has regular on/off switches (without dimmer). They are also three-way switches if that makes a difference. Thanks!

Some dimmers pass a very small amount of current in their off state. When incandescent bulbs are used the current is not enough to light them, but for some LED bulbs it is enough for them to light dimly.

The lights that are not on the dimmer are somehow seeing the current from the dimmer. If the neutral wires are being used for switching in one place or another (they should not be) there may be some interaction between the two circuits allowing that.

Put a regular incandescent bulb in one of the living room fixtures and see if there is any change. Do the same in the kitchen. If the problem does not occur with an incandescent bulb in the circuit, then the dimmer is causing the problem.

If that is not the case you may have to check the wiring at all points to make sure there is no neutral switching.

Electronic remote control or WiFi switches even if not dimmers could also be a cause for the same reason as dimmers.
