Why Do Lightbulbs Explode?

The sun has already set, and you’re on your way home. But as soon as you enter, you realise the lights are not working.

It turns out your light bulb is exploding. But what is the reason for exploding light bulbs? If the manufacturer does not include enough insulation at the bulb’s base, it can overheat, exploding the light bulb. However, there are more culprits behind exploding light bulbs.

Now, it always seems like the light bulb explodes at the wrong moment—not that there’s ever a good time to be left in the dark! Fortunately, our cell phone flashlight can now help us avoid smashed glasses while we replace the bulb.

However, it would be best to prevent such explosions to avoid inconvenient and often dangerous situations. So, why does a light bulb explode? In today’s guide, we’ll explore the causes of exploding light bulbs and how to prevent them.

Do Light Bulbs Explode?

Yes, but not in the dramatic way shown in movies or television shows. A light bulb explosion produces more of an internal “boom” or loud bang without breaking into a gazillion fragments. However, broken glass shards are hazardous, especially when pets or children are present.

Why Do Light Bulbs Explode?

There are several frequent scenarios among the numerous causes of why a light fixture unexpectedly explodes. Some of it is due to user mistakes, while others are due to the original design. This is not to say that the solution will be found here, but it does highlight some of the most common reasons that cause light bulbs to explode.

1. Improper Insulation

When the bulb’s metal base is not adequately insulated, there is an explosive danger. As the light bulb base gradually decays, this causes a pressure imbalance. This is a technical error on the part of the light bulb manufacturers.

2. Loose Connections

A loose wire and socket connection for your light fixture can increase the possibility of electrical current overheating the bulb, which causes light bulbs to explode in the loose sockets. The flow becomes irregular because it cannot establish strong contact. Loose socket connections, when the bulb is not sufficiently tightened, can cause the light bulb to explode.

3. Mismatched Bulb Wattage

When doing light fixtures, bulb wattage is critical. The light bulb must have the same wattage as the unit. A bulb that fits into a socket does not necessarily indicate that it was designed for that specific unit.

It is the user’s responsibility if light bulbs burst due to this fault. So, using a low-wattage light bulb as a guess is also not an option because you risk the light bulb exploding or power surge if it is in use.

4. Excessive Fixer Vibration

Flickering is caused by movement in or around the device. Overlooking the flashing will only harm the device and the LED light bulb. This is a frequent user mistake when using bulbs in earlier devices.

5. Greasy Hands

Homeowners usually underestimate the dangers of fixing light bulbs with oily hands. Any oil residue is unhealthy, but what’s overlooked is how much organic bodily oil creates problems. Hence, ensure you wear gloves while handling light bulbs to prevent this user mistake. And always remember to clean your light fitting regularly (and correctly).

6. Faulty Components

It is possible to purchase a defective light bulb, as with any of our factory-produced items. Faulty parts are typically found in the socket, filament, electrics, or glass. Determining which part was damaged might be difficult if a light bulb bursts due to a defective part.

It is the best way to double-check the light bulbs you buy at the store. Take everything out of the package and scrutinise them for any irregularities. In this instance, changing the lightbulb with a fresh one is the best action.

What Types Of Lightbulbs Explode?

Incandescent bulbs

Incandescent bulbs are the most common type of light bulb. They work by heating a thin filament inside the bulb until it glows. Incandescent bulbs are not energy-efficient and can explode if not installed or exposed to high temperatures.

Halogen bulbs

Halogen bulbs are incandescent bulbs that use halogen gas to increase the filament’s life. Halogen bulbs are more energy-efficient than incandescent bulbs but can still explode if not installed or exposed to high temperatures.

Fluorescent bulbs

Fluorescent bulbs work by passing electricity through a gas, which causes the gas to emit ultraviolet light. The ultraviolet light then hits a phosphor coating on the inside of the bulb, which converts it into visible light. Fluorescent bulbs are more energy-efficient than incandescent bulbs and last much longer. However, they can contain small amounts of mercury, which can be harmful if released into the environment.

LED bulbs

LED bulbs are the most energy-efficient type of light bulb. They work by passing electricity through a semiconductor, which emits light. LED light bulbs last much longer than incandescent bulbs and fluorescent bulbs and do not contain mercury. However, they can be more expensive than other types of light bulbs.

What Happens When Light Bulbs Explode?

Do not try to remove an exploding light bulb with your hand. The shattered glass pieces are jagged, and there is a risk of electrocution due to poor insulation. Clean up the explosion site and leftover glass so there are no risks while changing the light bulb.

Please turn off the breaker and gently remove the damaged lightbulb from its socket with gloves. Doing so ensures that the damaged bulb has cooled before you attempt to remove it. Finally, proceed to clean the space several times during the week.

Glass fragments are easy to overlook, yet they only need one to inflict catastrophic harm.
