For basic geometric shapes, the following arrangements should be used wherever possible, if there are no other obtrusions whitin the pool which could effect the spread of light. Further lights may be added to these designs for dark colour pool interiors. It is also assumed that the dwelling is located adjacent to the south wall of each pool.
In smaller sized pools with limited intrusions – a single light is sufficient. However it is always advised to position the light at the end of the pool to illuminate the length of the pool. This will provide a bright and even illumination.
Wherever possible, it is always recommended to position lights central, on each narrow end of the pool opposing each other.
The provides the best possible spread of the light and by facing the lights towards each other, ensures any obtrusion whitin the pool which may cast a shadow, will be illuminated by the opposing light.
Illuminating the width of a pool
In this scenario, as the pool is longer than the maximum distance the light can travel, the lights are placed in a row along the south wall and spaced evenly across.
Illuminating steps / swim-outs / ledges
Most pools designed today may have one or multiple types of steps, awim outs or safety ledges. All of which are designed to increase pool safety and function. To assist in pool safety it is always important to ensure these safety aspects are illuminated at night while still providing even illumination throughout the entire pool. A general rule for illuminating these features are to ensure lights are installed at a maximum depth of 300mm from the top of the pool, as steps and ledges are usually installed at a depth of 400mm.
