How many lights should I have in my pool?

Pool lighting not only improves the safety of swimming at night, but also creates a cosy atmosphere throughout the pool. A common question when designing and planning pool lighting is: how many pool lights should I install? This blog will explain how to determine the number of pool lights and the main factors that affect the number of pool lights.

How can I easily determine how many pool lights?
Based on the size of the pool, this is the most traditional way to determine the number of pool lights. Pools smaller than 3 metres can only have one lamp. After that, it is best to add at least one extra lamp for every additional 24 to 48 square metres of pool area. For example, a 4 x 8 pool needs 1 or 2 lamps, and a 6 x 10-12 pool is best with at least three lamps.

The above calculations only ensure that most of the pool area is covered with lights. If you want to achieve the best lighting results, in addition to the size of the pool, you need to consider the shape of the pool, the power of the lamps, the beam angle, even distribution, safety issues and individual lighting needs.

Additional factors to consider for optimal lighting results

The shape of the pool
Long, narrow pools need more lamps for better lighting. In addition, pools with a unique shape may require a more personalised arrangement to provide accent lighting while illuminating the entire pool.

Wattage of pool lights
Products with higher wattage provide brighter lighting, but bigger is not always better. The more wattage a pool light has, the more electricity it consumes when purchased and used. Moreover, this can lead to more heat build-up and possible glare problems.

Lower wattage pool lights are less bright and although they can avoid the problems of higher wattage lights, they can also affect the lighting effect of the pool. Therefore, we need to choose the right wattage for the lighting product based on the size and depth of the pool.

Streaming angle
The smaller the beam angle, the smaller the beam area and the further the beam distance. The range of lighting with a narrow beam angle is smaller, the light intensity in the centre is prominent, the light and dark dividing line is clear, the visual effect is stronger and suitable for important lighting.

However, when narrow beam angle pool lights are placed close together, the dividing line between light and dark becomes weaker. Some landscape pools use this approach to achieve unique lighting effects.

The wider the beam angle, the larger the radiation area and the shorter the radiation distance. A wide beam angle can illuminate a large area with a weaker dividing line between light and dark. Because the light is more diffused, a wider beam angle provides more even lighting.

Even distribution
Evenly distributed lighting is important for non-small pools and shaped pools. Not only does this provide a more coordinated and outstanding lighting effect throughout the pool, but it also eliminates dead spots in the lighting.

If you want more even lighting, switch to a product with a lower wattage and increase the distribution density.

Providing lighting for your pool not only adds to the aesthetics, but also prevents accidents. Besides illuminating the pool water, providing separate lighting for pool steps is a common practice to increase safety.

Individual lighting requirements
Many classic pools and their lighting designs are the result of a brilliant idea. There are many famous swimming pool designs around the world that are visited by tourists every year. These pools are designed to stand out and use a lot of pool lights or even light strips to enhance the visual effect. They look like dazzling works of art when illuminated by pool lights.

Don't disturb use
Some small pools have only 1 pool light installed to save costs. Unfortunately, if this one gets damaged, it will affect the normal use of the pool. A good practice is to use 2 recess pool lights or less powerful pool lights instead. Then, if one breaks down, you can keep using the pool at night until a replacement is found.

Appraising by pool area is an easier way to determine the number of pool lights. If you are looking for the best lighting and decorative effect, you need to take into account pool size, shape, lamp power, beam angle, evenness of distribution, safety and individual lighting needs. Finally, good luck with creating the pool of your dreams!
