Replacing bulb after bulb won’t fix this. The socket itself needs attention.
4. Dimmer Switch Incompatibility
Modern lighting has introduced a new class of problems.
Is the bulb labeled “dimmable”?
Is the dimmer rated for LEDs?
Is the wattage load within the dimmer’s range?
Older dimmers designed for incandescent bulbs can destroy LEDs quietly and quickly.
Symptoms of Dimmer-Related Failure
Buzzing or humming
Flickering at certain brightness levels
Bulbs failing within weeks
This problem often appears suddenly when someone “upgrades” to LED bulbs without upgrading the dimmer.
Enclosed Fixtures and Recessed Cans
Many modern fixtures look great but trap heat:
Fully enclosed glass fixtures
Recessed ceiling cans
Outdoor fixtures not rated for LEDs
LEDs are especially sensitive. Despite being “cool to the touch,” their internal electronics hate heat.
If bulbs are burning out mostly in one type of fixture, heat is likely the culprit.
6. Vibration and Structural Movement
This sounds minor, but it’s surprisingly common.
Garage door openers
Nearby traffic
Washing machines or dryers
Old floors that flex
Incandescent and halogen bulbs are especially vulnerable. Even LEDs can fail early if the driver components are stressed repeatedly.
If bulbs near fans or mechanical equipment are failing faster than others, vibration is a strong suspect.
7. Cheap Bulbs and False Economy
Not all bulbs are created equal.
Why Bargain Bulbs Fail Faster
Low-quality bulbs often have:
Poor heat management
Inferior electronics
Inconsistent manufacturing
