With the development of the times, the aesthetic appeal of swimming pools has become much more important than before. Villas, hotels, and private clubs, which are more focused on leisure and entertainment, have higher requirements for the appearance and lighting colors of their pools, necessitating the use of underwater swimming pool lights. Today, we’ll introduce some basic knowledge about the selection and installation of underwater colored lights.
First, the protection level requirements for underwater swimming pool lights
The protection levels of underwater colored lights are divided into dustproof and waterproof aspects. IEC standards stipulate that the internationally accepted protection marking symbols are as follows:
- Dustproof level: The national standard stipulates that the dustproof level of lighting fixtures is divided into 6 levels. Level 6 is the highest, and the dustproof level of underwater colored lights should reach level 6, marked with the symbol: IP6X.
- Waterproof level: The national standard stipulates that the waterproof level of lighting fixtures is divided into 8 levels. Level 6 is splash-proof, Level 7 is watertight, and Level 8 is pressurized watertight. Level 8 is the highest; underwater colored lights should meet Level 8 waterproofing requirements, indicated by the symbol IPX8. Considering both aspects, underwater colored lights should have a dustproof rating of Level 6 and a waterproof rating of Level 8, indicated by the symbol IP68.
Second, the safety standards for electric shock protection of underwater swimming pool lights
The national standard for electric shock protection indicators classifies lighting fixtures into four categories: Class O, Class I, Class II, and Class III. The national standard also clearly stipulates that underwater lighting fixtures for swimming pools, fountains, wading pools, and similar locations should be Class III electric shock protection fixtures. The operating voltage of their external and internal circuits should not exceed 12V.
Third, the importance of the rated operating voltage of underwater lights
The rated operating voltage of a lighting fixture is an electrical parameter that directly determines the operating environment of the light. The actual operating voltage must be consistent with the rated operating voltage. Otherwise, either the light source will be burned out due to excessive voltage, or the lighting effect will not be achieved due to insufficient voltage.
Fourth, How to Choose the Right Underwater Pool Lights
The selection of underwater colored lights should be based on the actual requirements of the project. The following aspects should be considered when rationally selecting underwater colored lights:
- Safety Function: In landscape settings, personal safety is the primary consideration when selecting underwater colored lights. They must comply with national standards and use 12V safety voltage underwater colored lights.
- Lighting Function: The lighting function mainly refers to the brightness of the light source. Different wattages of underwater colored lights can be selected based on the illumination height and projection area. Another element of the lighting function is the color of the underwater colored lights, generally available in red, yellow, green, blue, and white. The color can be selected according to the application, the object being illuminated, and the atmosphere to be created.
- Appearance and Shell Material: Although underwater colored lights are not very conspicuous, their shape and material are related to their specific gravity. If the specific gravity is too low, it will generate significant buoyancy, easily loosening the fixing screws and causing the light to float on the surface. If it is too heavy, the light frame will be difficult to support. Meanwhile, due to long-term use in water, the outer casing material should have a certain degree of corrosion resistance, and the surface paint layer should be durable.
- Economic Efficiency: The economic efficiency of underwater colored lights refers to the sum of the initial investment and operating costs. Generally speaking, higher-quality underwater colored lights have higher prices, longer lifespans, and lower operating costs. Conversely, lower-quality underwater colored lights, although cheaper, often cause blindness due to water leakage or electrical leakage, increasing operating costs and sometimes even affecting the acceptance of the entire project.
This concludes our introduction to underwater swimming pool lights. Due to the special application of underwater colored lights—they are electrical products operating underwater—they also have specific technical requirements. For more product information or solutions, please contact us.
