How Long Does LED lights Last.

While the LED lights are suitable for a good range of applications, there’s a limited lifetime for these lights. After a particular amount of your time period, the LED lights are destined to travel out of order and need a replacement as even repairs don’t seem to be possible.

Today, we’ll attempt to understand the common life of LED lights. we’ll also undergo a number of the foremost reasons that affect the lifespan of Led lights and damage them significantly.

How To Determine The life of an LED Light?

Before we take a glance at the lifespan of an LED light and also the factors that affect it, let’s try and understand how they calculate the common lifespan of an LED light, to start with. The LED lights have a really simple rule. When electrical phenomenon passes through the semi-conductive light-emitting diodes, it starts emitting protons that are visible to us as light.

Traditionally, the incandescent bulbs were determined by calculating the time it takes for half the bulb in a very batch to fail compared to the full batch. But, this method isn’t comprehensive enough to see the particular lifespan of an LED light as these lights don’t fail that easily. Instead, the LED lights change state gradually over time which makes the method even longer and tedious.

Lifespan of the led

Instead of waiting around to let the LED lights fail completely, their anticipation is decided when an LED reaches 70% illumination level compared to its original intensity. the remainder of the procedure is comparable because the results are concluded when 50% of LED lights of a batch have collectively reached the 70% candlepower mark. Depending upon the kind of LED, the results vary between 10000 and 50000 hours ARL (Average Rated Life).

The life of an LED light is represented in technical terms like L70, L50, etc. during this terminology, the amount represents the proportion of luminosity available on the LED compared to its rated output.

For example, an LED light with a anticipation of L70 of 50000 will fade up to 70% of its original capacity over the fundamental quantity of 50000 hours. Logically, the LED light with an L50 rating for the identical amount of hours will fade faster because it will fade up to 50% of its original capacity.

To understand the differences between the lifetime of various styles of LEd lights, we’d like to require a glance at various factors that have an effect on the lifetime of LED lights.

Main Factors That Affects an LED Light’s Lifespan

If you are taking a glance at a damaged incandescent bulb, you’ll easily know the rationale for the failure. In most cases, it’s thanks to external damage because the traditional lights don’t seem to be durable purposely. These lights would either get failed due to damage to the filaments. But, it’s not that easy within the case of LED lights.

The LED lights nowadays are very compact in design that creates it difficult to search out the foundation reason for failure as all of the minuscule components and connections can’t be seen by the naked eyes. In addiction to that, the LED lights do not have any independent moving part which may get damaged separately. Thus, every type of LED lights grow dimmer as time passes instead of turning off completely without delay

Here are a number of the common factors that damage the LED lights over time until eventually, they’re of no use. By understanding these factors thoroughly, you’ll be able to easily see the potential threats for your LED lights and apply some solution to avoid failure on your side.

Material and Manufacturing Defects

This is the foremost common variety of problem because it is incredibly hard to avoid in production companies. The LED lights are designed with a vital set of components that play a vital role in its working. The active region of an LED light consists of different components that operate coinceidentaly to form light.

If there’s a cloth or manufacturing defect on these parts, the LED lights will fail faster than expected. Even if the defect allows the light to show on within the beginning, these parts have better chances of getting damaged thanks to electricity and heat. Hence, it’ll sooner or later cause the LED to fail.

Most premium LED manufacturers make sure of those problems by selecting high-quality and sturdy materials for the development of the LED. Also, the matter may be avoided by eliminating hurdles within the manufacturing process to extend the lifespan of an LED light.

Electrical Overload

Electrical overload can potentially damage every kind of electronic devices whether it’s your TV, refrigerator, washer, or cooling. If the massive and expensive devices aren’t safe from electrical overload, the LED lights are under no circumstances an exception for this. within the case of LEDs, you may face EOS (Electrical Over Stress) which is caused when the input power on an LED light exceeds its design limit.

There may be many reasons for electrical over-stress. It will be caused by human error, damaged power supply units, Damaged onboard PCB of the LED lights, material defects, etc. When a surplus amount of electrical current is suddenly seasoned the crystal rectifier, it burns out tremendously faster. Therefore, you’ll see a sudden and brighter glow within the LED lights before they get damaged.

Electrical overload is an external factor which will be avoided by simply installing a stabilizer for your home or workplace. Even Led lights manufacturers introduce the static suppressor on their led lights devices that dampens an incoming power and minimizes the hazard for led light.


The main rule of the incandescent bulb was the illumination of filament thanks to increased heat on the filament caused by constant electric flow. As regular heat slowly introduces continuous permanent deformation in metals, the incandescent/ led bulb would fail much more quicker.

The LED lights on the opposite hand care for a way lower temperature level because the main components of the LED light don’t heat up the least bit. Even though, a small rise in temperature still occurs within the led lights because it could be semiconductor that contains natural resistivity to a flow of current. This excessive heat acts against led light and affects the lifespan drastically.

Apart from that, external heat sources also play a very important role in these matters. If led light is placed near an external heat source, it is a core semiconductor does not reject heat easily which reduces it’s lifespan. Hence, you’ll take this factor into consideration next time you’re installing LED lights to extend the lifespan of the LED lights.
What Is the common expectancy of an LED Light?

Now that you just know a number of the foremost factors that affect the anticipation of LED lights, let’s be told the overall lifetime of various styles of LED lights. As there are many various varieties of LED lights available within the market, there can’t be a definitive answer to the present question. Also, because of the differences in construction and performance of various LED lights, the range of average lifetime is extremely wide.

Following a range, you will determine whether the led light will operate flawlessly for 5 years, 10 years, or 1 year which is not an awfully decisive answer. Normally, the common lifespan of led lights falls between 10000 hours all the way to 50000 hours.

While there is not a definitive declare common expectancy of led light, we’ll assure you that it is still an exceedingly better option compared to the traditional light bulbs that consumes more power and have mean generation of 10000 to 50000 hours.


We hope that you simply are satisfied with the data available in our article today about the life of an LED light. Here, we’ve got presented a short discussion about the common lifespan of an LED light, how it’s calculated and what factors affect the lifespan of an LED light.

This information are surely useful for you within the future as you may be ready to choose an ideal option that guarantees longer reliability and lifespan. If you have got any queries regarding the data available here, you’ll reach us via the comment section.
