If other lights are burning out early around your home, you could have
what is called a floating neutral. It is the result of a poor connection of
the "white" neutral wire somewhere. The result is some outlets and lights
may receive more than the expected voltage and others less. The amount may
change as different loads are added or subtracted.
This can be dangerous. It it exist it can cause a fire and damage
appliances.
