How Long Do Led Lights Last – Problem Solved!

How long do LED lights last

Due to the power-saving and luminous feature, LED lights have replaced old-fashioned light bulbs in many places. Still, many people are questioning its actual lifespan. How long do LED lights last? Can they really last as long as the manufacturers claim? This post will provide the answers to these queries!

How Long Do LED Lights Last?

LEDs often have a lifetime of 5, 10, 16, or even two decades. Although these figures appear appealing to buyers, they may also be deceiving. In fact, a light source’s life expectancy depends on its daily use.

For example, an LED light can last for a decade according to its producer, but its actual lifespan is probably not the same. If you leave it outside, it can only survive seven years due to exposure to weather conditions. This LED bulb, however, can surprisingly last up to 13 years if it is kept in a room-temperature area and used not very often.

It is also worth noting that even if an LED light lives up to its maker’s expectations, it will undergo luminous decay, which decreases the LED’s brightness over time.

What Factors Contribute To How Long Led Lights Last?

Extreme Heat

The LED light’s chips and heat sinks are susceptible to hot temperatures, which means prolonged exposure to high temps can significantly reduce the lifespan of the LED light. 

If the heat of an LED light bulb exceeds 85°C, the heat sink’s life is cut short. According to LED lighting manufacturers, the temperatures of the lights should be lower than 85°C, which is good for the heat sink and the LED light’s life.

Other LED lights parts, like electrical equipment, are also sensitive to excessive heat. They’re designed to work at room temperature between 16 and 26°C, but they may be utilized in a garage, shed, or outside. LED lights work much better when the temp is less than 24 degrees C.

Usage Rate

It’s common knowledge that LED lights outlast traditional incandescent bulbs. However, many people are unaware that leaving these lights on for long periods causes them to degrade. Have you observed that their brightness decreases when you leave them running for lengthy periods?

In fact, every minute the lights on reduces the LED’s overall life. It stands to reason that using light when needed is important in maintaining the LED’s lifespan. 

The longevity decreases by the length of time it’s on.

In contrast to incandescent and halogen lights, the times of switching an LED light on and off do not affect the light bulb’s longevity. Regardless of how many times you turn it on and off, the LED keeps working, and the longevity only decreases by the length of time it’s on.

Electricity Currents

LED lights’ life expectancy is shorter if they are under greater currents than they should be.

LED light bulbs, like every other form of electrical equipment, have a specified working spectrum. Each LED can work with a specific electrical current or the amount of electricity passing across a circuit.

Once an LED bulb is working under an insufficient electrical current, the LED will not have sufficient power to provide the desired brightness. The advantage of this condition is that the LED can last longer since it does not work at its maximum capacity.

It is also good for the lights if a sufficient and stable electric current runs through the LEDs.

On the other hand, when an LED light is operating under an excessively high electrical current, it will glow brighter to consume all of the power produced by the circuit. This practice decreases the LED’s durability and risks overheating and burning out the LED circuit.

Reduce The Lighting Duration of LED

Although LED lights have a considerably longer life than incandescent bulbs, it is still good to shut off most interior lights before going to bed and switch off the outdoor lighting system in the morning. This practice may seem like a no-brainer, but you can improve the LED light’s longevity with this simple action.

Investing in a smart home network or a LED lighting with scheduled LED features is also a good way to control the LED lights. This tech allows you to select when the lights turn down automatically, ensuring that you are not misusing power or shortening the LED light bulb’s durability.

Let The LED Lights Cool Off

As previously stated, air temperature and bulb case heat are important elements in affecting the longevity of an LED light. Even if these bulbs produce less heat than incandescent bulbs, it doesn’t mean you should not cool them down. Allowing these LED bulbs to cool down will stretch their life and increase their lighting.

Thus, you should install those LED bulbs in a cool, dry environment with adequate room for the heat generated to disperse. Leave enough time for them to cool down before turning them back on.

Avoid Instant, Quick Turn-on/off

Even though we all know this is a no-brainer tip, it’s worth repeating. Rapidly turning on and off any light bulb might be harmful to its lifespan. This case is also true to apply to LED lights. 

Not only must the construction resist voltage instability, but it does not have time to recover before the following usage. As a consequence, their brightness dims, and their endurance shortens.

The Final Verdict

LED lighting is expensive to install, even though it is energy-saving and long-lasting. So, take appropriate care of your LED lights.

In short, how long do LED lights last depends on how users utilize them – often from 5 to 15 years. With the tips to increase LEDs lifespan, your LED can illuminate your cozy home for many years to come.
