Can power surges blow your light bulbs?

Yes, power surges can potentially blow or damage light bulbs. A power surge is a sudden increase in electrical voltage that exceeds the normal flow of electricity in your home or building's electrical system. This surge can cause a spike in the electrical current running through your light bulbs and other electronic devices, which may result in their failure or damage.
Light bulbs are sensitive to voltage fluctuations, and an excessive surge of electricity can cause the filament inside an incandescent bulb to burn out or break. Similarly, power surges can damage the electronic components in energy-efficient LED or CFL bulbs, leading to their failure.
To protect your light bulbs and other electronic devices from power surges, it is recommended to use surge protectors or install whole-house surge protection systems. These devices can help redirect excess voltage away from your electrical devices, preventing damage caused by power surges.

If you have had a power surge and need to get you home or building back on line, then contact your trusted local electrician to help check the problem and get it fixed right away.
