How Long Do LED Pool Lights Last?

It’s necessary to install LED pool lights in the swimming pool. It can delight you when you swim in a pool with bright lights and give you a better experience. For customers, they are very concerned about the lifespan of LED pool lights. Now, let’s try to find the answer how long do LED pool lights last?

Three Pool Light Types: INCANDESCENT, HALOGEN, And LED; Which One Lasts Longest?

It has a long history that people use lamps, from fire to grease, gas, and modern electric light. Nowadays, the development of science and technology makes people’s ideas come true, and lighting is used in various fields. For example, major shopping malls, tourist attractions, and so on. In recent years, lights have also been applied to water fountains, hot springs, pools, water parks, and other underwater lighting. The development of underwater lamps has also undergone several changes. People pursue to create more durable, less costly, and more environmentally friendly underwater lamps. There are three common types of underwater lights: incandescent, halogen, and LED pool lights, with LED lighting dominating the market. Now, let’s compare these three types of pool lights and see which one lasts the longest.


Incandescent lamps have a service life of about 800-1000 hours. The incandescent lamp uses electricity to heat the filament to an incandescent state and emits visible light through thermal radiation. The invention of the incandescent lamp met the lighting needs of people in its age and made great contributions to humankind. However, the incandescent lamp is gradually phased out due to its low light efficiency, short life, high power consumption, and high maintenance cost. Currently, some countries are beginning to plan for the phase-out of incandescent lights.


Halogen lamps are a type of incandescent lamp which is the result of the improvement of the incandescent lamp. There is the largest difference between halogen bulbs and other incandescent bulbs; that is, the glass shell of the halogen lamp is filled with some halogen gases. The invention of the halogen lamp has greatly extended the service life of the incandescent lamp. The service life of an incandescent lamp is almost four times that of an ordinary incandescent lamp, and it has higher brightness and light efficiency than an ordinary incandescent lights.


LED Pool Light

LED, a light-emitting diode, is a solid-state device that converts electricity directly into light. The characteristic properties of LEDs determine their numerous advantages, such as small size, low power consumption, environmental protection, high brightness, long life, etc. LEDs are light-emitting diodes (LEDs). Under the correct choice of current and voltage, the life of good quality LED pool light lamps exceeds 50,000 hours, far exceeding the life of traditional light sources.

After comparison, we concluded that LED lights last the longest.

At this point, why does pool lighting LED have the longest service life?

Why Do LED Pool Lights Last Long?

The reason for the long life of LED pool lights is that they utilize a special light-emitting principle. Unlike incandescent lights, LED lights do not need to heat a tungsten filament to emit light. Prolonged heating can cause the tungsten filament to thin or even even burn out, ending the life of incandescent lights.

LED is a cold light source, which passes an electric current between two doped regions (positive and negative) to directly convert electrical energy into light. This special light-emitting principle allows LED lights to have a longer life and at the same time be very energy efficient.

So, how can we buy durable LED pool lights for us consumers?

How To Choose LED Pool Lights For A Long-Lasting Time?

LED underwater pool lights, in all respects, are of a higher standard than ordinary lights. To buy a long-life pool lamp, we must pay attention to two aspects, the material and the other is safety.

The safety of pool lights

Then, it comes to the most important you need to focus on, safety. A qualified LED underground pool light must meet the IP68 standard to ensure no water gets in and no electricity leakage. A qualified pool lamp also uses a safe, low voltage design, namely 12v-24v. That is, the voltage design needs to be in line with the international standard of safety voltage below 36 volts. In case of leakage, it will not endanger life safety. Therefore, the most important thing in choosing pool lamps is to choose the pool lights produced by the regular manufacturer.

Good quality low voltage pool lights are very safe and you can use them with complete confidence.


In addition to needing to meet IP68 protection ratings, underwater pool lights as an electrical device must also meet certain safety and performance standards. These certification standards vary by country and region. Choosing a certified product ensures its safety and reliability.

The Material of LED Pool Lights

Stainless Steel Pool Lights

Stainless Steel Pool Lights

Today, many LED pool lights have housings made of stainless steel.

It has many types of stainless steel. Still, the main application in the underwater lamp housing is stainless steel 304 and stainless steel 316. The underwater light will work in the water for a long time after installation, so we must choose the corrosion-resistant material, the stainless steel pool light. Is stainless steel 304 different from stainless steel 316? Which is better? The first is in appearance. The two do not look very different. Secondly, 304 and 316 are austenitic stainless steel. 316 is 304 added molybdenum and has more nickel element, so 316 stainless steel seawater rust prevention ability is better than 304. 316 is generally used in the offshore environment. In terms of price, 316 stainless steel is more expensive than 304 stainless steel because of the addition of molybdenum and nickel elements in 316.

Stainless steel 316 is undoubtedly a better material. Still, stainless steel 304 is also a great option if you have a limited budget. But for saltwater pools, it is best to choose stainless steel 316 underwater lamps. Anyhow, it is good to buy LED pool lights that work for you after carefully considering them.

Plastic Pool Lights

Plastic Pool Lights

Stainless steel pool lights tend to sell for more than plastic pool lights. If you are on a budget, then plastic pool lights are the way to go.

They are very durable as the body of the light is made with antioxidants during the manufacturing process. These products are equally good in quality while being affordable.


In addition to paying attention to the lamp shell material, you should also pay attention to the lens material.

The lenses of our LED pool lights are made of tempered glass or PC.

PC lens has good strength and toughness and is not easy to break, so it is also called a safety lens. PC material has the advantages of a lightweight, high impact strength, high refraction index, good electrical insulation performance, environmental protection, etc. Everything has its disadvantages. PC lenses should not be used in an overheated environment; otherwise, they will cause deformation. But if it is applied in the pool, this disadvantage can be ignored. Therefore, PC lenses are quite the perfect material.

Tempered glass is called a safety glass, which is the glass’s surface with compressive stress. When glass bears external strength, it can offset surface layer stress, which upgrades bearing ability. Besides upgrading bearing ability, it helps to strengthen wind, heat, and cold resistance performance, etc.

Although the lens is destroyed by an external force, the LED pool lights that use tempered glass as lampshades will not lead to serious danger. Its features decide that tempered glass is not only durable but also safe.

The above are common pool light materials. As a matter of fact, there are more materials that can be used to manufacture pool light housings and lenses. You can read Material Selection of Swimming Pool Lights to learn more about their properties.

After installing the LED pool lights, how should we maintain the pool lights to prolong their life?

How To Maintain LED Pool Lights For A Longer-Lasting Time?

Here are a few maintenance tips, do the following to ensure that you will have a durable pool light.

  1. Check and repair the LED swimming pool lights regularly. When it is found that the pool light is dimmed, check-in time to find out the reason. If it doesn’t work completely, fix the lights and replace them in time. Don’t delay. In addition to checking the lights, check for water inflow in the light.
  2. Use a controller compatible with the pool light. The current LED swimming pool lights are very advanced, with a variety of control methods. Such as WIFI control, remote control, and external control. Long-term use of a controller that is not compatible with the pool light can also impair the life of the pool light.
  3. Clean the swimming pool regularly to prevent the accumulation of excessive impurities, which will pollute the water quality and damage the underwater lights in the long run.

Over the past decades, LED swimming pool lamps have been constantly updated to accept the supervision and test of the market and the majority of users. Today, you can see all kinds of LED pool lights in the market. For example, there are floating pool lights, recessed pool lights, nicheless pool lights and wall mounted pool lights. Customers have more serious standards for LED pool lights, encouraging the pool lights suppliers to innovate. Now LED pool lights can meet users’ needs in terms of performance or aesthetics. So, choose a LED pool light for your swimming pool, enjoy your pool, and have a good time with your friends.
