7 Reasons Why Light Bulbs Burn Out Quickly

    Some of us may have had the experience of coming home, turning on the lights, and seeing the light bulb sputter at us as it dies away and goes out after a series of flickers. While some may have seen them irregularly fizzle in the evening after they have been up for a while.

    Our home light bulbs emit light by distributing electric current through a thin tungsten filament. The filament heats up and gives off light. Gradually, the filament oxidizes and becomes frail, until it breaks apart and the bulb flickers. As the oxidation occurs over time and builds up, the light bulb should die randomly. For those who live in a house with electricity knows, this is not what happens. Below are the 7 reasons why light bulbs burning out quickly:

Loose Wiring Connections

    If a bulb isn’t tightly fixed in the socket, it can flicker every now and then. You just have to tighten the bulb in its socket to solve it. Another problem may be a loose wire connection where the circuit wires attach to the fixture. Shut off the power and inspect the wires to make sure they are properly connected to the screw terminals. The bulb socket can also have damaged contacts that result in connection issues. If this happens, replace the socket or the fixture. Regularly loose connections, either with the wire connections or at the socket, can break down the bulb quickly that result in flickering. These loose connections raise the electrical resistance and heat traveling through the filament, which can reduce its life.

Short Circuit

    If a short circuit happens it can result in a light bulb to burn out quickly. In an electrical system circuit line, a short circuit can lead to the light fixture, as well as all other components on the circuit to suddenly become dark. Once a short circuit happens, it can affect electrical resistance, which increases the flow of electricity through the circuit. The abrupt increase in current flow trips the circuit breaker or blows the fuse, and interrupts the electrical current. This causes the lightbulb and the rest of the house to go dark.

Too Large Bulbs for Light Fixture

    Many light fixtures come with labels of their maximum bulb wattage to utilize in the fixture. When you notice that a lightbulb burns out too abruptly in some lamps or fixtures, open the fixture cover and inspect if the bulb wattage is enough or too much for the rating of the fixture. This isn’t an issue with the LED bulbs, which work at moderately low wattage, but it is a common problem with old incandescent light bulbs, where it is easy to go over the rating of the light fixture by utilizing too large light bulbs. This generates excessive heat, shortening the bulb life, and possibly melting down the insulation on the fixture wiring.

Wrong Type of Dimmer Switch

    When lightbulbs in a fixture operated by a dimmer switch break down in no time, there is a possibility the wall switch utilizes not the standard type of dimmer. Outdated dimmer switches were made for the regular incandescent bulbs only, and when you have LED bulbs in the light fixture, the standard dimmer may break the wiring at the bottom of the bulb and result in it to immediately burn out. There are types of dimmer switches manufactured to complement LED light bulbs, and changing the old dimmer addresses the problem.

High Line Voltage

    When the issue is with the fan lights, the high line voltage is not at fault. If the issue occurs with all your light fixtures, it may be a high-voltage problem. Light bulbs are designed to work at a particular voltage, such as 125 volts. When the voltage goes over their specification, they will burn out in no time. In this case, you have to check the line voltage and read with a digital multimeter at wall storage. When you have a reading going over 110 to 120 volts, you need to contact a professional to fix the issue.

Extreme Fixture Vibration

    Another reason for bulbs burning out is extreme fixture vibration. One example is the light fixture in a ceiling fan. If a fan blade gets unstable, the fan begins to shake, and the vibration bounces the filament in the bulb and reduces its life. The same issue occurs with light bulbs in garage door openers. You can secure a rough-service bulb to deal with this problem. These bulbs come with heavy-duty filaments to resist vibration. 

Damaged Socket Tab

    The tiny metal tab of a light bulb socket is the heated connection that supplies electricity to the bulb. When the socket tab of the socket is held down too far, it may not connect with the bulb. It’s not that the bulb has broken down, but it does not make an electrical connection with the socket. To deal with this, unplug the fixture or shut off the power to the fixture, then utilize a wooden popsicle stick to adjust the tab up. Then attach the bulb back and check if it works. This quick-fix may not work with old sockets as the metal tabs are brittle or have lost their spring completely. In such a case, the best possible solution is to change the light bulb socket or the light fixture itself.

Wrong Type of Bulb

    While they are known for working longer than incandescent bulbs, compact fluorescent light bulbs have the reputation for going bad before their shelf life. This type of bulb is designed to have a lifespan of about 10,000 hours, however, when you have some of these bulbs, but this number may be exaggerated for those who have used them. Its lifespan will also reduce when the light fixture is switched on and off regularly. A 10,000-hour rated bulb can only last up to 3,000 hours when it is switched on and off too often in a day.

    If you have light bulbs that must be replaced much more frequently than they should, contact the experts of Electricians Service Team. We have a team of certified electricians who can help diagnose the problem and upgrade your electrical wiring, faulty fixtures, install poor electrical outlets, or offer you recommendations that can reduce risks linked to the affected lighting fixture or fixtures.
