Main information
What it could mean
A fault in the lighting circuit affects several light points at once, usually from a fault in that circuit's protection or shared wiring.
Safety first
Check if the lighting breaker has tripped in the switchboard before assuming several bulbs blew at once.
Next step
If the circuit doesn't recover once the breaker's reset, the fault is in the wiring or a specific light point dragging down the rest.
Frequently asked questions
Is it normal for several bulbs to blow at once?
Unlikely as a coincidence; a fault in the shared circuit is more common than several bulbs failing together.
How do I know if it's the circuit or one specific light point?
If resetting the breaker only leaves one point failing and the rest come back, the problem is at that specific point.
Could it also affect the sockets in the same area?
Depends on the layout; lighting and sockets are usually on separate circuits.
