How Long Do LED Street Lights Last?


One of the most significant changes in lighting has been the introduction of LED lighting solutions. LEDs offer multiple benefits for users. They are eco-friendly and efficient as well as safe. Because of their long-lasting benefits and energy savings, LED street lights are popular. LED lights last longer than other lighting devices and typically last up to 50,000 hours. But, like other lighting devices, LED lights can be damaged or broken by a variety of factors. What is the life expectancy of outdoor LED street lights? How can you prolong its lifespan? This article will give a detailed introduction. If you want to know more about LED street lamps, read on.

What are the factors that affect the service life of LED street lights?

There are many factors that affect the service life of LED lights. By understanding these influencing factors, you can avoid the problems that can occur and ensure that the LED street lights last long enough.

  • LED street light controller

The controller of LED street lights controls and monitors the photovoltaic module status. It also manages batteries and keeps them operating. The controller maintains the street light’s load and provides a stable operating environment, particularly in emergencies like a low battery or Undervoltage. The controller’s high-precision, the stable function will be a crucial part of your control system.

  • LED driver

The life expectancy of luminaires that are operated beyond their recommended power requirements can be significantly reduced. A reliable power supply, also known as a driver, is essential for LED street light bulbs to maximize their power output and extend their life expectancy. This ensures an optimal supply of electricity, which eventually allows for the control and regulation of voltage. It is a good idea to invest in high-quality LED street lights with integrated drivers.

  • Environmental temperature

The temperature of the area where an LED bulb is placed can significantly impact the life expectancy of that luminaire. An increase in ambient temperature can cause damage to the driver and chip of enclosed lighting fixtures. This can drastically reduce the life expectancy of the luminaire. It is recommended that LED street lights outdoor are installed in areas where heat can be dissipated, and cooling can occur.

  • Storage battery

A storage battery should have relatively consistent performance for LED street lights. To protect against flooding or other mishaps, the battery must be installed properly during construction. This will impact the life expectancy of the LED streetlight.

  • Heat emission

High temperatures can cause heat sinks and chips in LED street light bulbs to be sensitive. The LED luminaire’s life expectancy will decrease if it is heated above 85 degrees Celsius. The temperature of the bulbs should not exceed the mentioned temperature. This is not only beneficial for the heat sink but also for the longevity of the street lights LED.

The LED street light’s life expectancy depends on many factors, such as the controller, light source, and more. LED lamps that are used for over 1,000 hours are less bright than they were before. Some can last more than 100,000 hours if used as indicators for small-power LEDs. However, high-power LED street lamps have a service life of fewer than 100,000 hours. How long a LED street light will last depends on its environment and the quality of the electronic components. Similar to the bucket principle, the component with the shortest life determines the lifespan of an LED street light bulb. But, you don’t have to worry too much. You can get the most from your investment by taking good care of your LED lights.

How can you prolong the lifespan of LED street lights?

An LED bulb’s average life expectancy is 50,000 hours. However, even the most efficient lighting systems can have problems if the proper equipment is not used. The life expectancy of your bulbs can be decreased by improper installation, wrong fixture selection, and poor use. However, this doesn’t mean that LED street lights can’t be made to work even better. As one of the best Chinese LED street light manufacturers, Kanglight has extensive experience with LEDs. Learn our tips to extend the service life of your LEDs and more.

1. Focus on the light decay detection report

The first thing you should look for when choosing LEDs is the light decay detection report. This is an important link. Some units are self-tested, and others are tested by a third party. It is best to choose test reports from an approved body recognized by the Semiconductor Alliance. They are more reliable.

2. Don’t ignore the LED street light structure

The LED street light structure is a significant issue. One of the main causes of the significant light deterioration in the actual use of street lamps is that this problem receives little attention from the lighting sector. After only a few periods of external use, the street lamp’s entire surface is caked in dust, significantly reducing its cooling capacity. Given this circumstance, the structural layout of street lamps is crucial.

3. Pay attention to the light source

Even though there is a short slab, the light fade of an LED street lighting fixture produces a barrel effect and makes it unavailable. Light decay is more challenging to manage since a decent radiator does not always address the issue of light source degradation. The light source’s packaging contains a significant error. The COB light source’s silica gel is too thick. Thus it needs to be packaged as thinly as possible to help the chip’s luminous surface dissipate heat. This is the cause of the COB light source’s poorly controlled light decline.
In addition to the above, it is strongly recommended that people only buy high-quality (with warranty) LED street lights. Cheaper alternatives can be vulnerable to premature malfunctioning.


In conclusion, you can get the most from your investment by taking good care of your LED lights. And it is worth mentioning that buying high-quality (with warranty) LED street lights can avoid premature malfunctioning. As one of the best Chinese LED street light manufacturers, Kanglight can offer you good-quality LED street lights, such as cobra head LED street lights. All our products are safe and reliable, thanks to years of research and development, production skills, and strict testing. Lights’ maximum warranty is up to 10 years.
