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. The advantages of pool LED lights are as followings: First, LED pool lights help you swim or move easier by providing a clearer view for you. Second, it has a comfortable atmosphere playing in the pool with pool lamps. Third, swimming in the pool with lights at night is safer. Today the most popular pool lamp is LED pool lights. Why are pool lights LED so popular? Yes, because of its low power consumption, long service time, and green. For the customer, our main concern is how long a LED pool light will last. Now, let’s try to find the answer how long do LED pool lights last?

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.

Three pool light types: INCANDESCENT, HALOGEN, and LED; which one lasts longest?


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, incandescent light bulbs are banned in most countries.


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 lamp.


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). With the right choice of current and voltage, the lights’ lifespan is about 8,000 hours, which is almost 10 times the lifespan 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 principle of the incandescent lamp is that electric energy will light emitting tungsten wire to heat and light. After a long time of heating, tungsten wire will age or even burn out, so the life of the incandescent bulb is ended. The special luminous principle of LED determines its long service life. By converting electric energy directly into light energy, unnecessary energy loss is reduced, the heat is less, and there is no aging and burning phenomenon. LEDs are entirely encased in epoxy, making them firmer than lamp bulbs and fluorescent tubes. There are no loose parts inside the lamp as well, making the LED less vulnerable to damage.

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 material of LED pool lights

First of all, the shell material, most of the current LED pool light, is made of stainless steel.
shell of pool light

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 underground pool lights that work for you after carefully considering them.

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

pool light tempered glass lens

The LED pool lamp produced by our company is 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.

The lens of LED pool lights using tempered glass have good quality. Whether the lampshade is made of tempered glass is also one of the standards for us to buy lamps and lanterns.

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 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 lamps produced by the regular manufacturer.

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, underwater pool lights, recessed pool lights, and wall mount 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.
