Why does bulbs blow

One reason why your light bulbs might be blowing out often is that the light bulbs you are buying are cheap and low quality. The elements in cheap bulbs are much thinner and any surge of power, however slight, will break them.

The cheaper bulbs are not meant to last long and will continue to break at a rapid pace no matter how new they are. Always go for more expensive, better quality light bulbs saves you money in the long run. A loose connection in the lamp holder can also cause the light bulbs to blow. However, if the supply in your home is higher — this can cause your light globes to burn brighter and, consequently, to burn out much faster. If you have found that multiple bulbs around your home have a shorter lifespan than expected, high voltage could be the culprit.

In this situation, it is recommended that you contact a qualified electrician to check and measure your electrical supply. Should any issues be detected, they will be able to provide you with professional recommendations for an effective solution to the problem.

Depending on the location of lighting fixtures within your home, if any are subject to excessive vibration, this could provide another explanation as to why your bulbs keep burning out quickly. This is because movement can cause the filament in the bulb to jiggle and burn out quicker than normal. Similarly, a fixture that has not been correctly installed and is not well-secured can be subject to excessive vibration.

Rough service light bulbs are an alternative option, with a thicker filament to make them more resistant to excess vibration and movement. Speak to a professional electrician about the different types of light globes available, and the best options for your home. Another reason for bulbs to burn out too quickly could be due to poorly installed or loose wiring. Damaged or loose wires can result in fluctuating current, which can destroy the filament in a bulb.

However, if you are not an electrical pro; loose or damaged wiring is not something to be messing about with on your own. If you have any concerns regarding the wiring surrounding your lights, or anywhere in your home, it is important that you call a licensed electrician to carry out a thorough inspection and attend to any wiring issues ASAP.

However, screwing the light bulb into a socket too tightly can make the socket less efficient. If you over-tighten a bulb, it bends the spring back and creates a small electrical arc.

Vibrations break the fragile filaments found inside incandescent light bulbs and cause the fragile electronic parts inside CFLs to separate. It might be worth getting a hardier bulb. Although most homes in the UK are assumed to have v electricity supplying them, overvoltage can be a common problem. Always go for more expensive, better quality light bulbs, its cheaper in the long run. A loose connection in the lamp holder can also cause bulbs to blow.

This is because the circuit is not completed as tightly as it could be and the electricity may have cause to "arc" or jump across the contact, rather than simply flowing through it. When this happens it produces more heat in the fitting than is expected or catered for by the bulb, and the bulb can blow. The same can happen if the spring loaded connection in the bulb holder is slightly loose.

This will cause electricity to arc across the contact, cause too much heat and blow the bulb. This can very often be diagnosed by looking at the contact on the bottom of the bulb to see if it is pitted. Arcing electricity effectively melts the metal it is arcing onto This is how arc welding works so if the bulb contact is being subjected to arcing, tiny little indentations occur, called pitting.

It is sometimes possible, if the live connection in your light switch is a little loose, for this to happen here also. Heat will be generated and it is possible, though very very remote, for the bulb to blow as a result of this. This makes the problem seem rather bigger than it actually is.

The reason for a blowing lamp tripping an MCB is that the lamp element gets thinner during its life to the point where it breaks at the thinnest point, this point will melt just before failure.

As mentioned above, make sure you have turned the power off before you do any maintenance whatever. Read our projects on electrical safety and Part P building Regulations.

Be careful out there! Assuming that you have not bought really cheap bulbs, and they keep blowing then there are other problems that are the cause. Further, we have had 3 LED bulbs burn out in less than a year. Any ideas wat could be the cause?
