we had electrical work done outside out condo & now we have a super weird electrical issue. check this out
The issue of string lights remaining dimly lit (or "ghosting") after being switched off—particularly after utility work—is a common phenomenon with LED lights, often caused by small amounts of residual voltage or "leakage current" in the circuit. The timing suggests the utility work likely caused a small shift in your home's neutral or ground voltage, which the highly efficient LEDs are now picking up as a faint power source.
Here are the most likely causes and solutions based on your situation:
Why It's Happening (Post-Utility Work)
- Leakage Current/Induced Voltage: Even when a switch is off, tiny amounts of electricity can be "leaked" from nearby wires or the dimmer switch itself. Because LED strings require very little power, this residual energy is enough to make them glow faintly.
- Neutral/Ground Issue from Utility Work: Utility crews often work on neutral connections. If the neutral connection in the panel is loose or shifted, it can create a slight backfeed through the ground, which can cause LEDs to glow faintly
it's going to be torture to get the management company to own up to it
