LED Lighting in Pool

How to find, how to choose?

LED technology has revolutionized swimming pool lighting, with benefits both economic (energy efficient) and playful with its palette of colors and moods. Offers increasingly numerous and very different technological prowess, how to find when we pool professional?

First, a reminder of the art


In Europe, the supply current of a floodlight is obtained by processing alternative in mainstream secondary current 12 volts AC.The use of a safety isolating transformer is required and the wiring section connecting the projector to the transformer is directly related to the power absorbed during lighting and the distance separating them.

LED floodlight for pool

This type of projector consists of a light source composed of LEDs and associated with a control module (driver) managing the current in the LED and providing them with different features. These two parts are assembled in a closed and sealed medium that can be used in permanent immersion.


Compared with an incandescent lamp 300W pool, which lasts about 1,500 hours, the LED is announced by zephyrledlights for periods of up to 100,000 hours. What really ? In laboratory conditions, it is true, an LED has a very long life. These manufacturers data imply a perfectly stable current and above a operating temperature of 25 ° C. In swimming, the current supplied varies depending on the power grid and unfortunately the temperature contained in the projector more higher than in the laboratory, significantly affecting the life of the LED. In addition, the LED does not operate alone and require on-board electronic components which themselves do not have the same life expectancy and also vary depending on the operating temperature. The lifespan of the end product, your LED projector is directly dependent on the component that has the shortest life span.

Light intensity

The level of light intensity, we must also be careful. Indeed, what is the true brightness of the finished product? Take the example of an LED that emits 100 lumens (1) in laboratory condition. Product X is manufactured using 12 LEDs of this type and therefore can emit 1200 lumens. This is the theoretical light intensity. In reality, we must take account of losses caused by the current limitation related to the management of temperature but also to lighting loss due to optical (window) … It is the effective luminous intensity . To know the real or effective light intensity, only a laboratory measurement allows the determination.

Power and power consumption

The power or energy consumption in watts (2) is very important for an LED luminaire. When replacing a 300W PAR56 lamp with a LED lamp, there is usually no change

the existing electrical installation, provided that its power does not exceed the original lamp. By cons, construction, choice of the projector relative to its power consumption, determines both the cable section to install but also the transformer and therefore influences the final cost of installation. For the user least one LED projector consumes, the larger the realized energy savings.

In conclusion

You understood, choose an LED projector for swimming involves an understanding of its operation and clear readability of its performance. White, color, intensity, power, durability, economy, environmental protection and price are the key elements that will motivate your choices, then ask yourself these key questions:

  1. Lumen

This is the luminous flux emitted from a light source at its base.

  1. Watt

Electricity is the power unit of a system that is measured by multiplying the current (amps) and voltage (volts) the current drawn.
