It’s no secret that lightbulbs don’t last forever. Even if it feels like an exceptionally long time since you last replaced them, lightbulbs all burn out at some point. Some burn out prematurely, and some do not. Sometimes it may be only days or hours after they were first installed.

There are reasons why your lightbulbs frustratingly burn out and there are ways to make sure it doesn’t keep happening.

There are important things you need to make sure you’re taking into consideration when it comes to installing new lightbulbs and expecting them to work. Whether it’s an issue of mismatched voltage, vibration problems, bulb types, or electrical problems, there’s plenty of causes for a faulty lightbulb burning out but we’ve got some common ones outlined.

Below are some of the most common causes for a lightbulb to burn out in a home prematurely.


All lightbulbs have an intended voltage and all lightbulb bearing appliances also have a voltage requirement. If you’ve got a bulb intended for a smaller voltage amount than what the appliance is designed to give off, then the bulb will burn brighter and at higher energy that intended and burn out quicker. In some cases, this can take only days or blow right when you plug it in. Make sure the voltage requirements match.

Bad Connection

Many times, a bad bulb isn’t bad at all, but is suffering from a loose connection in its socket. If a bulb is loose in the socket, then it will flicker on and off and may even lose connection all together. Tightening the connection can help but if you have a chronic issue then you may want to inspect the socket and the bulb for necessary repairs or refitting.

Short Circuits

Sometimes a lightbulb going out is misdiagnosed. This is why it can be important to seek help from a professional. A lightbulb going out could have nothing to do with the bulb at all but be the result of a short circuit in the system. A sudden burst of energy, from a lightning strike for example, can cause the system to overflow with current and shut down as an emergency measure.

What If My Lightbulb Is Hot?

Lightbulbs that are mismatched to sockets can become physically hot and burn out from a lack of properly dispersed heat. This is usually the case with lightbulbs that are too big for their sockets.

What If I’m Still Having Problems?

If you exhausted other options, the answer may be that the overall voltage in your home is too high. You may not notice this until bulbs start blowing out. A professional electrician can help you diagnose this problem.
