Main information
What it could mean
Flickering LED bulbs usually come from incompatibility with a dimmer switch, a loose connection, or a faulty internal driver in the bulb itself.
Safety first
Not usually a serious electrical risk, but new and worsening flickering is worth checking.
Next step
Assessed whether the flicker happens with any LED bulb at that point (pointing to an installation issue) or only with one specific bulb (pointing to a bulb fault).
Frequently asked questions
Why do LED bulbs flicker more than traditional ones?
LEDs are more sensitive to small current fluctuations and to incompatibilities with older dimmers.
Could the flicker indicate a connection problem?
Yes, if it happens with different bulbs at the same point, it can point to a loose connection there.
Is it fixed by switching to a different LED model?
For dimmer incompatibility, yes; for a loose connection, the light point needs checking.
