The answer to 'why is my light fixture power surge' is that a power surge is a sudden, brief increase in the voltage of the electrical current. This can be caused by various factors, such as lightning strikes, faulty wiring, or issues with the electrical grid. Symptoms of a power surge include flickering or dimming lights, damage to electronic devices, and the light fixture itself may stop working.
To troubleshoot a power surge issue, first check the circuit breaker to ensure it hasn't tripped. If the breaker is fine, the problem may be with the light fixture itself or the wiring. You can try replacing the light bulb or inspecting the fixture for any loose connections. If the issue persists, it's best to call a licensed electrician to diagnose and resolve the problem, as power surges can be a safety hazard and require professional expertise to fix.
