Are LED Pool Lights Safe?

LED pool lights

Nowadays, LED has become the main stream product of swimming pool lighting. Compared with traditional halogen lamps, LED swimming pool lights are more energy efficient, have many optional emitting colors, and are environment friendly. For users, it also has the most crucial feature – safety. This article will take you through a comprehensive understanding of why LED swimming pool lights are safer.

Safe working voltage

The voltage of standard LED swimming pool lights is 12V or 24V, which is lower than the 36V safety voltage. This means that even if the swimming pool has an electric leakage problem, electric shock in the water will not harm the human body.

Despite the low voltage of LED swimming pool lights, the brightness is still excellent. The light efficiency of an ordinary LED light chip is 2-3 times that of a traditional halogen lght chip. The top brand LED light chip efficiency of LED lights is even 6-7 times of traditional halogen lights. When other interference factoirs are not considered, a 20W LED light has a brightness equivalent to a halogen light with above 150W at most.

According to the power calculation formula, P = UΙ. When the electric current is constant, the power is reduced by half, and the voltage is also reduced by half. Therefore, the LED swimming pool light still has high brightness at low voltage.

LED swimming pool light chips are divided into SMD and COB. There are some differences in the technology and process of different manufacturers, but they generally consist of chips, brackets, silver glue, gold wires, and epoxy resin.

These parts do not contain mercury, so there is no need to worry about mercury leakage caused by broken lamps. The LED manufacturing process uses semiconductors and precious metals, which is also the main reason for the high cost of LED manufacturing.

In order to reduce the selling price, some manufacturers will save costs on materials and processes. Therefore, you need to beware of LED pool lights priced much lower than similar products because they are prone to problems.

Don’t need to worry about getting cut

Traditional incandescent lights, fluorescent lights, and energy-saving lights all have glass shells or light tubes. These structures take up a lot of space and are also very easy to break. Please pay attention to avoid bumping and being cut by glass fragments when careying, installating and using them. LEDs do not have this structure, so there is no such trouble at all.

Strong waterproof performance

The manufacture and application of LED in the field of swimming pool lighting is very mature, and many manufacturers have launched swimming pool lights for underwater lighting environments. LED swimming pool lights with strong waterproof ability will not leak electricity and have a longer service life. IP68 rated underwater pool lights usually use the following measures to prevent water from entering the light body :


Structural engineers design lamps strictly according to international protection standards and test repeatedly to ensure the reliability of product design.

Waterproof material

The common materials of underwater lighting are stainless steel, plastic, glass, brass, and aluminum, and their water-proof ability is excellent.

VDE waterproof power cord

Reliable manufacturers use waterproof power cords that are VDE certified.

Resin filled

A unique waterproof method injects the entire light source with a sealing colloid to completely isolate the possibility of water and dust entering. This method is suitable for LED lights with good heat dissipation and low power. Excessive temperature will melt the colloid and reduce the service life.

Sealing rubber ring

It is often found at the joint between the power cord and the inside of the lamp to prevent water from entering through the gap of the power cord.


In order to unify standards and quality, some countries or international organizations have formulated relevant specifications and certifications. The safety and quality stability of LED lights that have passed relevant certifications are more reliable.

When selecting LED swimming pool lights, you can ask the seller or manufacturer if they have a locally recognized certification.

Choose compliant parts

In addition to the pool lights, good accessories can reduce safety hazards and extend the life of the fixtures. Transformers, power supplies, plugs and power cords all meet certification standards. When choosing a transformer or power supply, it is also important to reserve a certain amount of power space according to the fixture to prevent overloading.

The above content has let us understand that LED swimming pool lights are very safe, but we still need to pay attention when installing them.

If necessary, short circuit protectors can be added to the pool lighting system to make the pool environment safer. Circuit design and installation should be done in strict accordance with codes.

LED pool lights are very safe. All we need to do is to check with the seller or manufacturer at the time of purchase to confirm the product’s waterproofing, rating certifications, and select compatible components. Follow strict specifications during installation and equip your lighting system with a short circuit protector if needed. That way, you can enjoy your pool time without worrying about safety.
