1. Arcing Electricity:
When the bottom of a light bulb doesn’t make a snug connection with the hardware in the light socket, it can cause electricity to arc between the socket and bulb. You may not know this is happening just by looking at the bulb, but arcing electricity can generate excess heat, leading to a blowout. If you think this may be happening, remove the bulb and check the bottom for dark spots or pitting—the telltale signs of arcing electricity.
For safety’s sake, you may want to contact an electrician to investigate and repair this issue. But there is one common, simple problem that causes light bulb blowouts you can easily fix on your own. Look into the problematic light bulb socket—you should see a small brass tab that is slightly raised.
If a light bulb is screwed in too tightly, this tab can be flattened, which can lead to arcing. You can bend this tab upward again with your fingers or a pair of pliers, but only if the fixture is completely disconnected from electricity. If it’s a table lamp, simply unplug it. If it’s a wired fixture, shut off the corresponding circuit breaker and use a fresh bulb to confirm that the socket is disconnected.
2. Loose Connections
A loose connection in the lamp holder can also cause the light bulbs to blow. When the circuit is not tightly completed, it makes the electricity jump and not flow. When the power jumps, it creates more heat in the fitting than recommended for by the bulb to handle forcing it to blow.
3. Cheap bulbs
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.
4. Mechanical Vibrations
Filament light bulbs are often very delicate, especially if they’re cheaply made. Mechanical vibrations, over a long enough period, can contribute to sudden blowouts by causing the filament to snap. These vibrations can come from nearby appliances, sound waves, second-floor foot traffic and many other sources. When vibration is the culprit, switching to an LED bulb is a sure-fire fix.

How To Fix Your Blowing Bulbs
3 places to check if your light bulb keeps blowing out. Also, always consider buying high-quality energy efficient light bulbs like LEDs.
- Your bulb supplier
- The wire connections inside your bulb holder
- If the spring loaded connectors are working properly inside the bulb holder
For high voltage
Put on a dimmer or variable transformer
Ask the power company about the voltage problem – is it neighborhood-wide?
