Smart Bulb "Flickering" When Dimmed
4.5
The bulb works fine at 100% but starts flickering or strobing at 10-20% brightness.
Symptoms
- Strobing light
- Flickering
- Buzzing
Possible Causes
- Incompatible wall dimmer
- Low quality LED driver
- Voltage fluctuations
Step-by-Step Fix
1
Remove Wall Dimmer
Smart bulbs MUST have 100% power from the wall; use a standard switch.
2
Update Bulb Firmware
Manufacturers often fix dimming curves in software.
3
Check for "Power On" Behavior
Ensure the bulb isn't resetting due to a loose connection.
When to See a Technician
Smart bulbs use PWM (Pulse Width Modulation) to dim; if the incoming power isn't steady, they will flicker.
