How Long Do LED Lights Last?

Are you interested in buying LED lights but don’t know how long they last?

Lighting technology continues to evolve, with LED lights being the centre of attention when it comes to an extended lifespan. Since lighting accounts for 10% of the average electricity budget, it’s essential to invest in lighting technology that is both affordable and safe for the environment. 

As LED lights find their way into businesses and homes, understanding their lifespan becomes crucial for consumers wanting to make informed choices. If you’re curious about LED lighting, keep reading to learn how long this lighting technology could last.

Understanding LED Technology

Light Emitting Diodes (LEDs) generate light through a process called electroluminescence. Unlike traditional incandescent bulbs that rely on heating a wire filament to produce light, LED lights convert almost all of their energy into light. This results in a significantly lower energy footprint. 

LED lights also come in various colours without you needing filters. This occurs from the varying materials used in the semiconductor. In turn, businesses can control the colour and intensity of the light by changing the materials and the design of the commercial LED light.

The absence of hazardous materials like mercury, which is found in compact fluorescent lamps (CFLs), makes LEDs an environmentally friendly option. Business owners can appreciate their longevity and positive impact on energy consumption and the environment. 

What Is the Average LED Lifespan?

On average, LED lights can last between 25,000 to 50,000 hours. This lifespan is longer than traditional incandescent bulbs, which typically last around 1,000 hours. LEDs also overthrow compact fluorescent lamps (CFLs), which have an average lifespan of about 8,000 to 10,000 hours. 

It’s important to note that the actual lifespan can vary based on several factors, including the quality of the LEDs, operating conditions and your usage patterns. 

For example, if you use an LED light for about 3 hours per day, it could last for more than 20 years. This duration not only reduces the frequency of replacements but also contributes to long-term cost savings for business owners. This is because LEDs consume less energy and require fewer replacements compared to traditional lighting options.

Factors Influencing LED Lifespan

LED lights are renowned for their durability and longevity, but several factors can influence their overall lifespan. Understanding these factors is essential for business owners looking to make informed decisions about their lighting choices.

Here are the factors influencing LEDs: 


One of the primary factors affecting LED lifespan is temperature. LEDs are sensitive to heat, and excessive heat can significantly reduce their long-term duration. High temperatures can accelerate the degradation of the LED components, leading to a shorter lifespan. On the other hand, cooler environments can contribute to an extended lifespan. 

To eliminate these temperature-related issues, ensure the LEDs have proper ventilation and avoid installing them in enclosed fixtures that may trap heat. 

Quality of Components

Not all LEDs are the same, so it’s essential to choose a lighting option that has high-quality materials. High-quality LEDs use superior materials in their construction, making them more resilient to wear and tear. This means that cheaper lights degrade faster and have a shorter lifespan. 

Usage Patterns and On/Off Cycles

LED lights are highly efficient when it comes to energy consumption. However, frequent on/off cycles can impact their lifespan. The stress caused by rapid temperature changes during frequent cycling may contribute to quicker degradation of the components. 

To avoid this issue, consider minimising unnecessary on/off cycles, especially in areas with motion sensors or occupancy detectors. 


Tips for Making LED Lights Last Longer

While LED lights have an impressive lifespan, there are proactive measures business owners can take to further extend their longevity. 

Below are some tips for making LEDs last longer in your business: 

Proper Installation Matters

The way you install LED lights can significantly impact their performance and lifespan. You must ensure that you follow the manufacturer’s guidelines to avoid draining the light. Proper ventilation is essential to dissipate heat, especially in recessed fixtures. It’s also worth avoiding tightly enclosed spaces that can trap heat, as excessive heat can shorten the lifespan of LEDs.

Mind the Voltage

LED lights have specific voltage ranges that they can operate in. Using the correct voltage is essential for their optimal performance and duration. Voltage fluctuations beyond the recommended range can stress the components and reduce the lifespan of LEDs. 

Consider using voltage stabilisers or surge protectors to regulate and protect the electrical supply.

Be Aware of Operating Temperature

Temperature control is essential for the LEDs to function. LED lights perform best within a specified temperature range. Therefore, maintain a consistent ambient temperature in the environment where you have installed the LEDs. As mentioned before in the affecting factors, avoid exposing them to extreme temperatures, as this can affect both short-term performance and long-term lifespan.

Control Ambient Conditions

Did you know that humidity levels can also affect LEDs? While LEDs are generally less sensitive to humidity than traditional bulbs, excessive moisture can still affect their electronics. Install LEDs in areas with moderate humidity levels and avoid placing them in locations prone to water exposure or condensation.

Optimise Usage Patterns

LED lights are suitable for frequent switching, but optimising usage patterns can contribute to their extended lifespan. You should consider using dimmers to reduce light intensity when you don’t require full brightness. This process not only conserves energy but also reduces stress on the LED components. 

Regular Cleaning and Maintenance

Keep your LED lights clean to ensure optimal light output and heat dissipation. Dust and dirt can accumulate on the surfaces, affecting both the aesthetics and performance of the LEDs. 

To clean the LEDs, gently wipe the surfaces with a soft, dry cloth to remove any buildup. Regular maintenance checks will also identify and address issues, which can prevent potential problems that could impact lifespan. 

Comparisons with Other Lighting Technologies

As business owners increasingly seek energy-efficient lighting solutions, comparing the lifespan of LED lights with traditional lighting technologies becomes essential. 

We delve into how LEDs fare against incandescent and fluorescent lights below: 

Incandescent Lights

Incandescent lights have an average lifespan of 10,000 hours, making them less effective than LED light bulbs. LEDs also win over incandescent lights in energy efficiency since incandescent bulbs waste a lot of energy as heat. So, choosing LED lights as your go-to light fixture will make your business more environmentally conscious. 

The NSW Government Energy Savings Scheme (ESS) can also help you save 80% on your lighting costs when using LEDs.  

Fluorescent Lights

Fluorescent lights have a longer lifespan than their incandescent counterparts but still fall short when you compare them to LEDs. This is because the average lifespan of fluorescent lights ranges from 8,000 to 10,000 hours.

Fluorescent lights also have drawbacks, such as the presence of hazardous materials like mercury and the flickering. On the other hand, LEDs contain no hazardous materials and provide instant, flicker-free shine.


Long-Term Cost Savings

While LEDs might have a higher upfront cost, the long-term cost savings are immense. The extended lifespan of LEDs means you don’t have to spend more on replacements and maintenance. Not to mention the reduced energy consumption, which leads to reduced electricity bills over time.


LEDs stand out as durable, energy-efficient winners in the lighting industry. With an average lifespan ranging from 25,000 to 50,000 hours, LEDs can reduce your energy bills and carbon footprint.
