Changed the bulb. Still flickering?
Sometimes the obvious answer is the right one.
Sometimes it isn't.
A recurring flicker could involve the fixture itself, a driver, lighting controls, a connection, the circuit supplying it or something else in the electrical system.
The useful part is often the pattern.
Does it happen to one fixture or several?
Does it happen at a certain time?
Does it happen when equipment starts?
Did something change before it began?
Those details can help an electrician narrow down where to start looking.
If you've replaced the obvious thing and the problem keeps returning, stop treating the symptom and find the cause.
