The choice of luminous flux of pool luminaires depends on the brightness of the ambient light and the size of the pool. The absorption rate of cold white light with higher color temperature is lower than that of warm white light in water. This is because blue light is absorbed by 5%, green light by 3% and red light by 16% after a metre of exposure to water.
Therefore, the use of cold white LED lamps has two advantages: higher LED light efficiency and lower absorption in water.
For rectangular swimming pools of different widths, the approximate guiding values of light flux required by LED lamps are as follows:
The wires used must be special underwater wires, which can match the diameter of the copper core specified by the lamp manufacturer. If the lamp does not have wires, be sure to follow the manufacturer's recommendations to seal the connection. The same requirements apply to the distribution box and the waterproof and sealed distribution system.
Ideally, the connection of the wire to the lamp is done at the lamp factory, which requires the wire length to be determined when the lamp is placed. For the values listed above, it is recommended to keep the illumination of the pool environment below 100lx to make the water more visible. For rectangular pools, for more even illumination, fixtures are recommended to be mounted on either side of the long side, at a 90-degree beam Angle, with fixtures spaced about half the width of the pool.
