Smart Bulb "Ghosting" (Glowing when off)
4.5
The smart bulb stays very dimly lit even when you turn it off in the app.
Symptoms
- Faint glow at night
- Flickering when off
- Buzzing
Possible Causes
- Incompatible dimmer switch
- Residual current
- Cheap LED driver
Step-by-Step Fix
1
Replace Dimmer with Standard Switch
Smart bulbs have their own dimming; they don't work with wall dimmers.
2
Swap with Different Brand
Higher quality bulbs (like Hue) have better isolation from residual current.
3
Check Wiring
Ensure the neutral wire is correctly connected if using a smart switch.
When to See a Technician
Even a tiny amount of "leakage" current can light up an efficient LED bulb.
