In this article, we will explore the question “how long do LED strip lights last?” by discussing the average lifespan of LED strip lights, factors that affect their longevity, and how to properly maintain them. Additionally, we will also cover the benefits of LED strip lights to help you understand why they may be a good investment for your home or business.
Components of LED Light Strips
LED light strips are composed of individual light-emitting diodes (LEDs), flexible printed circuit boards (FPCBs), resistors, and other components. These components are assembled using surface mount technology (SMT), ensuring a compact and flexible design.
Protection for Outdoor and Underwater Use:
To enhance durability, some LED strips are protected with silicone or polyurethane glue. This coating provides resistance to moisture, dust, and other environmental factors. These protected strips are ideal for outdoor and underwater installations, ensuring longevity in harsh conditions.
IP Rating and Lifespan:
IP rating, which indicates the level of protection against ingress of solids and liquids, affects the lifespan of LED strips. While higher IP ratings provide better protection, they can hinder heat dissipation. This reduced airflow leads to increased operating temperatures, potentially shortening the lifespan of the LEDs.
Surface Mount Device (SMD) LED:
The Surface Mount Device (SMD) LED is a critical factor in determining the overall lifespan of an LED strip. SMD LEDs come in various sizes, with smaller sizes (such as 2835 and 5050) offering higher brightness and longer lifespan than larger sizes. The quality and efficiency of the SMD LEDs directly impact the durability and reliability of the entire strip.
Protection of Outdoor LED Strips
Outdoor LED strips require protection against the harsh elements they face. This is achieved through silicone or polyurethane (PU) glue coatings. These coatings act as a protective barrier against moisture, dust, and other environmental factors that could damage the delicate LED components. By providing this added layer of protection, outdoor LED strips can withstand the elements and maintain their performance over time.
Impact of IP Rating on LED Strip Lifespan
The IP rating of an LED strip indicates its level of protection against dust and water ingress. Higher IP ratings provide enhanced protection, but this can come at a cost to heat dissipation. Heat dissipation is crucial for the longevity of LED strips, as excessive heat can shorten their lifespan. As a result, LED strips with higher IP ratings, while more durable, may have a slightly reduced lifespan compared to those with lower IP ratings.
Factors Affecting LED Circuit Lifespan
The lifespan of an LED strip is largely determined by the lifespan of its LED circuit. Several factors can influence the lifespan of the LED circuit, including the operating conditions, such as temperature and humidity, as well as the design of the LEDs themselves. The L70 method is commonly used to estimate the lifespan of LEDs, indicating the hours of operation until the brightness decreases to 70% of its original level.
LED Lifetime and the 70% Rule (L70)
LED lighting, including LED strips, exhibits a gradual decline in brightness over time. To determine when an LED strip has reached the end of its useful life, the industry uses the “”70% Rule,”” or L70. This rule defines the point at which an LED strip has lost 30% of its original brightness, resulting in a remaining intensity of 70%. This level is generally considered too dim for practical use.
Calculation of L70
The L70 value is determined through the LM-80 test method. This method involves subjecting LED samples to a controlled temperature and current environment for 6000 hours. During this period, the luminous intensity of the LEDs is measured and recorded. The resulting data is documented in a report, providing a reference for the expected L70 value.
Challenges in Lifespan Testing
Testing the lifespan of LEDs presents challenges due to its extended duration. To achieve the typical 50,000-hour lifespan, continuous testing would take up to 6 years. This lengthy process can be impractical and costly.
TM-21 Extrapolation Algorithm
To address the challenges of lifespan testing, the TM-21 extrapolation algorithm has been developed. This algorithm utilizes data collected from the initial hours of LM-80 testing to estimate the LED lifetime. By extrapolating the data, the testing duration can be significantly reduced, providing a more efficient and realistic approach to estimating the expected lifespan of LED strips.

How does the power source affect the lifespan of LED lights?
Stable Power and LEDs
LED strip lights can be likened to marathon runners in the lighting world—they can persevere as long as they receive a consistent energy supply. The power supply serves as their essential lifeline, the key to their enduring performance.
A reliable power supply isn’t merely important; it’s indispensable for LEDs. It’s akin to the fundamental pairing of bread and butter or the essential role of wheels for a car. Without it, functionality is compromised. LEDs specifically thrive on stability. Consistent and stable power sustains their luminosity, allowing them to radiate brightly over extended periods.
However, when the power supply experiences fluctuations, it’s akin to altering the gravitational forces during a marathon run. One moment, you feel weightless like a feather, and the next, you’re burdened like lead. An unstable power supply disrupts the smooth functioning of an LED strip light, impacting its performance and longevity.
Fluctuating Power
Fluctuating power supplies act as the Achilles’ heel for LED lights, drastically reducing their lifespan, akin to a lumberjack swiftly chopping down a tree with an axe.
The relationship is straightforward: superior-quality power supplies directly translate to extended longevity for LEDs. It’s comparable to the difference between fresh organic produce and fast food—clearly, one leads to better outcomes in terms of health.
Another inadvertent method of damaging LEDs is by overdriving them with excessive voltage. Picture your LED light as a small boat sailing in calm waters (stable voltage). Suddenly, an enormous wave (high voltage) crashes in unexpectedly! This surge can inflict severe damage, resulting in reduced lifespan or immediate failure.
Here are some recommendations:
- Always opt for quality power supplies specifically designed for LED lights.
- Avoid subjecting your LEDs to high-voltage surges.
- Regularly inspect your lighting setup for any indications of instability or voltage fluctuations.
How does heat affect LED strip lights?
LEDs, much like any other electronic device, generate heat. However, they differ significantly from old incandescent bulbs, which often doubled as miniature heaters. LEDs operate at lower temperatures but are not exempt from the laws of physics. Let’s delve into how heat impacts these small yet remarkable light sources.
LED lights generate heat
LEDs emit light through a process known as electroluminescence, where electricity passing through a semiconductor results in light emission. Despite its fascinating nature, this process isn’t entirely efficient, leading to some energy loss as heat.
Unlike in other electronics where heat is typically an incidental outcome, in LEDs, it can directly influence their performance and longevity.
Heat: A Light Dimmer and Color Changer
Excessive heat adversely affects the output and color quality of LED strip lights. It’s analogous to running a marathon in scorching weather—you tire quickly and probably don’t perform optimally.
Elevated temperatures can prematurely dim an LED or alter its color rendering index (CRI). Over time, bright white lights might shift to a yellowish or reddish hue, deviating from the expected lighting quality.
Heat sink for LED lights
Effectively managing heat is crucial for prolonging the lifespan of LED strip lights, primarily through the use of efficient heat sinks. Think of these heat sinks as the air conditioning units for LEDs.
A quality heat sink absorbs surplus thermal energy from the LED chips and disperses it into the environment. This practice maintains lower operating temperatures, ensuring consistent light output and color quality over time.
Various types of heat sinks are available, such as:
- Aluminum extrusion
- Stamped metal
- Cast metal
Each with its advantages and disadvantages. Nonetheless, any heat sink solution is preferable to allowing LEDs to overheat and deteriorate.
The higher the temperature, the shorter the lifespan
The correlation between higher operating temperatures and reduced lifespans is simple—higher heat leads to shorter lifespans. It’s akin to leaving ice cream out in the summer—we all know how that ends!
For every 10°C rise in temperature at the junction (where electricity enters), an LED’s lifespan typically decreases by about half. So, if you want your strip lights to outlast your latest diet plan, keeping them cool is the key!
Using LED strip lights continuously also affects the lifespan
The precise lifespan of LED strip lights is a common inquiry, yet not easily answered. Multiple factors contribute, but let’s delve into how daily usage impacts their longevity.
Hours Used Per Day
Consider a high-quality LED strip light with an approximate lifespan claim of 50,000 hours. If left on continuously (24/7), that amounts to just over five years! Conversely, using it for an hour daily could extend its lifespan to over a century. The duration of daily usage directly correlates with the overall lifespan—more usage leads to a shorter life, while less usage extends it significantly.
Switching Frequency
The frequency of turning your lights on and off matters too. Research indicates that frequent switching can impact lifespan. Although seemingly trivial, each switch-on causes an instant power surge, adding stress to the LED strip lights’ internal components. While LEDs are more durable than traditional bulbs, excessive switching throughout the day can affect their longevity.
Use for a long time without stopping
Allowing LED strip lights to run continuously without breaks can also affect their lifespan. Similar to humans needing breaks from work, these lights require intervals. Extended uninterrupted usage can cause overheating, subsequently reducing their life expectancy. Although leaving them on overnight might create a desirable ambiance, moderation in usage is advisable.
Usage Patterns: Continuous vs Intermittent
Different usage patterns influence LED strip lights differently. Continuous use exposes them constantly to electricity and heat, leading to faster wear-out. Conversely, intermittent usage allows for cooling down periods, potentially extending their lifespan.
However, bear in mind that these factors aren’t the sole determinants of lifespan. Other crucial aspects such as product quality and operating conditions (e.g., exposure to sunlight) significantly contribute to how long these lights will serve you reliably.
Electrical Currents in LEDs
LEDs, a cornerstone of modern LED lighting, operate by harnessing the flow of electrical currents through a semiconductor material. This current stimulates the emission of light, making LEDs an energy-efficient and versatile lighting solution.
