Light Bulbs Burning Out Too Frequently

When light bulbs burn out faster than expected, the cause is usually one of several common issues. Understanding these helps you solve the problem or know when to call an electrician.

Voltage fluctuations are a common cause. If your home's voltage runs high (above 120V), bulbs burn hotter and die sooner. This can be tested with a multimeter or by an electrician. Voltage issues may originate from the utility company or from problems in your home's wiring.

Loose socket connections cause arcing that damages bulbs. When a bulb isn't making solid contact with the socket, electricity arcs across the gap, creating heat and damaging the bulb's filament or electronics.

Vibration kills bulbs, especially incandescent ones. Ceiling fans, garage door openers, or fixtures near HVAC equipment may subject bulbs to constant vibration that damages filaments.

Enclosed fixtures without adequate ventilation trap heat. Bulbs - especially LEDs - can overheat when enclosed, dramatically shortening their lifespan. Look for bulbs rated for enclosed fixtures if yours are covered.

Using bulbs with higher wattage than the fixture rating is dangerous and burns out bulbs quickly. Always check the fixture's maximum wattage and use appropriate bulbs.

Poor quality bulbs simply don't last. While cheap bulbs seem economical, quality LEDs from reputable manufacturers last much longer and save money over time.
