Voltage Fluctuations

Ever find yourself wondering why light bulbs burn out so often? It's a common issue we often overlook. Despite their small size, these twisted light bulbs face various challenges, leading to quick burnouts. Factors like bulb type, environmental conditions, and usage patterns contribute to this recurring problem. In this blog, we'll explore the secrets behind why light bulbs burn out fast, shedding some light on the familiar yet mysterious issue many homeowners face.

Why does my porch light keep burning out?

  1. Poor Quality Bulbs

Choosing low-quality bulbs for your porch light can be a crucial reason bulbs keep burning out. When you notice your porch light constantly going out, it could be a sign that the chosen bulbs lack the resilience to resist your typical environmental factors.

These low quality bulbs often fail to meet the demands of outdoor orientation and fluctuations. To ensure your porch light never burns out frequently, invest in high-quality bulbs that can be used in your outdoor environment, providing reliable and long-lasting brightness.


  1. The wrong type of Bulb

Choosing the wrong bulb for your porch light can cause it to burn out quickly. If the bulb doesn't match your light fixture or isn't suitable for outdoor use, it may struggle to handle weather changes and electrical needs. So, if you're dealing with burned-out bulbs or lights failing too soon, check if you're using the right type.

Pick bulbs made for outdoor lights that fit your porch light to make it last longer. When bulbs match your fixture, they don't burn out often, keeping your porch light shining and dependable.


  1. Voltage Fluctuations

Voltage changes are a common cause of light burnout. When the electrical supply to your home suddenly shifts, it stresses the light bulbs. To protect your porch light from voltage fluctuations, think of it as putting a shield around it. You can use a voltage stabilizer or surge protector – like a caretaker for your light. They make sure the electricity flowing to your porch light stays constant. It is essential because sudden changes in electricity, either too much or too little, can stress out the light bulbs and make them burn out quickly.

By using these protective devices, you keep a stable power supply to your porch light, making the bulbs last longer and saving you from the hassle of changing them frequently.

Short Circuit


  1. Old Wiring

Old or damaged wiring can cause your light bulbs to burn out quickly. As wires age, the protective layer around them wears down, making them vulnerable to damage and creating an unsafe electrical situation. This aging wiring can disrupt the stability of your porch light's power, resulting in bulbs failing too soon. Upgrading to modern wiring doesn't just improve safety; it also ensures a steady power flow to your porch light.


If your home's wiring is old, it's a good idea to consult a qualified electrician for an assessment. This proactive measure can significantly reduce the chances of light bulbs burning out in the same socket and improve how your porch light bulbs perform.


  1. Humidity

When it's humid outside, your porch light can face some challenges. Imagine it's like your light is a superhero, but humidity is a tricky villain. It sneaks into the light's home (fixture) and causes problems for its electrical parts. This can lead to the light not working well and burning out too soon. To save the day, give your superhero light a special suit – use weather-resistant fixtures and regularly check for any signs of water. This way, your porch light can stay strong, shine bright, and beat the humidity villain, making it last longer.


  1. Overloaded Circuits

Picture your home's electrical system like a busy road and every device as a car on that road. If you connect too many devices to the same circuit, it's like having too many cars trying to use the same lane – things get crowded, and the system can't handle the load.


The overloaded circuit affects the bulbs' lifespan, making them burn out faster. To avoid this, try spreading out your devices on different circuits, like cars taking separate lanes on the road. This way, your porch light can shine bright without facing the traffic jam of overloaded circuits.


  1. Loose Connections

Think of the wires in your porch light like puzzle pieces—they must fit snugly together. If they don't connect properly, it interrupts the flow of electricity and stresses out the light bulbs. This inconsistent connection can make the bulbs burn out faster.


Keep an eye on the wires in your porch light to ensure they fit together well and help everything work smoothly, and your porch light bulbs will last longer. If you see any loose wires or connections, fix them immediately. Doing this ensures your porch light works well, and you won't need to change the bulbs too often.


  1. Insects Infestation

Insects can cause your porch light to burn out frequently. When bugs infiltrate the fixture, they can disrupt the bulb’s normal operation, causing it to overheat and fail prematurely.


To safeguard your light, consider regular cleaning and maintenance. The covers act as a protective shield, preventing insects from interfering with the light. With its protective cover and regular cleaning, your porch light is equipped to shine brightly for a longer duration. Just as superheroes need their gear, your porch light requires regular cleaning and appropriate covers to deter insects and maintain its luminosity.


  1. Short Circuit

Imagine a short circuit as an unexpected shortcut in your home's electrical system. When wires accidentally connect, electricity takes a quicker route, disrupting the normal flow and stressing your porch light bulbs. This disruption makes them burn out faster. To avoid this, ensure your home's wiring is in good condition. Regular checks by a skilled electrician can detect and fix possible short circuits. This provides a smooth flow of electricity, making your porch light bulbs last longer and reducing burned light.

How do I stop my LED from burning out?


  1. Frequent On/Of Cycling

Imagine your porch light as a runner in a race. Frequent on-off switching is like making the runner start and stop repeatedly, exhausting them. Similarly, your porch light's filament gets tired from the constant on and off, causing it to burn out faster.


To avoid this, consider motion sensor lights or energy-storing light bulbs as helpful assistants for your porch light. These forever light bulbs reduce manual switching, creating a stable environment for your bulbs. Just like having a steady pace in a race preserves energy, using these alternatives keeps the life of your porch light bulbs.


  1. Wrong type of Dimmer Switch

Using the wrong dimmer switch can harm your porch light bulbs in two ways. First, it might cause frequent burn-out light, making your bulbs die quickly. Second, it can impact how well your bulbs work and how long they last.


To avoid these problems, it's crucial to check and use the right dimmer switch for your porch light. Make sure it's compatible with the type of bulbs you have, like LED bulbs. This way, you ensure that your porch light functions well and your bulbs don't burn out before their time.


  1. Age of Bulbs

Like shoes or toys get old, light bulbs also have an age limit. Even good-quality bulbs wear out naturally over time. To avoid sudden surprises when the light goes out, it's a good idea to change them regularly, like how you get new shoes when the old ones get worn out.

This way, your porch light stays reliable, and you won't have to deal with unexpected darkness. Keep an eye on bulb lifespan, and when it's time, give them a fresh start for a brighter porch. Also, it is recommended to use energy-storing light bulbs or small LED light bulbs because they don't burn out frequently.
