Three Reasons Your Lightbulb Keeps Going Out

When your light bulb goes out and you replace it, it's not a big deal. However, when you notice that the same bulb keeps going out — it's a sign that you have an electrical issue taking place. Learn about some of the scenarios that could cause this sort of issue and how you should address it.


A common reason that homeowners experience recurrent issues with a light bulb is due to the fact that they don't have the right bulb installed in the first place. The voltage rating on the bulb connector is not a suggestion, it's a requirement. Installing a bulb with a higher voltage rating than the fixture can accommodate will cause it to blow, and to do so quickly. 

Choosing low-quality bulbs made from cheap materials that can't withstand an occasional power surge, are also not the best bulb choice. You should also choose higher quality bulbs. Not only can they better withstand surges, but they last longer overall. 


If the light bulb that you are having issues with is installed on the ceiling below an upper level, the movement could be to blame. In older homes or those that have not been built with the highest quality materials, it's common for the ceiling below an upper level to vibrate when a person walks across the floor on the upper level.

Over time, this vibration causes the bulb to move, which puts it at risk. Fortifying the fixture is a great way to eliminate this concern, as it will make the connection less vulnerable to vibrations that are occurring around it. 


If the connection where you install the light bulb is wobbly, you should know that it's just a matter of time before the bulb fails. Electricity is intended to flow at a steady rate. When the connection between the fixture and the bulb is not secure, the power delivery will spike, instead of remaining steady. 

When power spikes, the amount of heat that is delivered to the bulb also increases, which will ultimately reduce the lifespan of the bulb. Have an electrician inspect the connection to see if it needs repaired. In some instances, the connection can be tightened, but in other instances, it might need to be replaced, especially if it's an older fixture.  

When it comes to an electrical issue, it's always best to contact an electrical professional for repairs. Only an electrician can make the electrical repair safely and correctly.
