Considerations for Choosing LED Underwater Lights

LED underwater lights, also known as aquarium lights or submersible lights, are LED lights installed underwater. They are primarily used for lighting large swimming pools, fountains, large fish farms, aquariums, and marine biology museums.

1. Basic Protection Level of the Fixture:
• Dustproof Level
  According to national standards, the dustproof level of lights is divided into six levels, with level 6 being the highest. The dustproof level of LED underwater lights should reach level 6, denoted as IP6X.
• Waterproof Level
  According to national standards, the waterproof level of lights is divided into eight levels. Level six is splash-proof, level seven is water-tight, and level eight is pressure water-tight. Level 8 is the highest, and LED underwater lights should meet the requirements of level 8, denoted as IPX8.
  Based on the above requirements, the dustproof level of LED underwater lights is level 6, and the waterproof level is level 8, denoted as IP68.
2. Safety Features
   For landscape locations, the choice of LED underwater lights prioritizes personal safety. It is imperative to use LED underwater lights with safe voltages of 12V/24V, as per national standards.
3. Materials of LED Underwater Lights
   LED underwater lights are immersed in water for long periods, and their working environment consists of water or other conductive liquids. Therefore, their casing materials should have certain anti-corrosion, waterproof, dustproof, leak-proof, and corrosion-resistant features, with a firm surface paint layer. Additionally, the appearance and material of the light fixtures are related to their density. If the density is too low, it will create significant buoyancy, easily loosening the fixing screws and causing the light to float to the surface. However, if it is too heavy, it won't support the lamp base.
4. Lighting Function
   Lighting function primarily refers to the brightness of the light source. LED underwater lights of varying wattage can be chosen based on the height and area of illumination. Given their uses for products, landscape decorative effects, cultivation, etc., consumers have different requirements for the brightness and color of LED underwater lights. Generally, there are five colors: red, yellow, green, blue, and white. The choice can be made based on the application scenario, the object of illumination, and the atmosphere to be created.
5. Economic Efficiency
   The economic efficiency of LED underwater lights refers to the sum of the one-time investment and operating costs of the lights. Generally, the higher-quality LED underwater lights are more expensive, have a longer lifespan, and have lower operating costs. Conversely, lower-quality LED underwater lights often fail due to leaks or electrical faults, not only increasing operating costs but also affecting the overall project acceptance and the personal safety of the construction personnel.
