Properly lighting a swimming pool is more than just screwing a bulb into a niche. The choice of the number of floodlights, their luminous intensity, and their placement determines both the safety of night swimming and the ambiance of the pool. With the DURAVISION range by Duratech, and in particular the VISION Spectra DVM, VISION Spectra DVS, and VISION Allegro models, it is possible to precisely adapt the lighting to the size, shape, and liner color of each pool. Here is how to calculate your needs and choose the right model.

How many LED floodlights should be installed for optimal pool lighting?

For a standard 8x4 meter (32 m²) rectangular pool, the basic rule remains the same: count one floodlight every 15 m² approximately, which generally means 2 to 3 well-distributed light points. Duratech recommends a reference luminous flux of 100 to 150 lumens per m² for a pool with white or light-colored walls, which corresponds to a total requirement of about 3200 to 4800 lumens for this 32 m² pool.

The DURAVISION range covers a wide power range depending on the chosen model:

  • VISION Spectra DVM: up to 1675 lumens, available in white and RGB, in 50, 100, and 170 mm diameters.
  • VISION Spectra DVS: up to 3950 lumens, available in white, Tuneable White, and RGB, also in 50, 100, and 170 mm.
  • VISION Allegro: up to 5500 lumens, available in white, warm white, and RGBW, with dimming function and free color choice.

For a standard pool, two 170 mm VISION Spectra DVS floodlights are more than enough to reach the recommended threshold, while a single high-end VISION Allegro can cover a good portion of the pool thanks to its higher power and wide beam angle.

What are the luminous flux recommendations based on the desired ambiance?

The brightness level to aim for mainly depends on the intended use of the pool at night:

  • Soft and relaxing ambiance: 80 to 100 lumens/m². The VISION Spectra DVM in white, or the VISION Spectra DVS in Tuneable White, are perfectly suited for this cozy look.
  • Bright lighting for parties and receptions: 150 to 200 lumens/m². The VISION Spectra DVS in RGB or the VISION Allegro in RGBW allow for a variety of colorful atmospheres while ensuring sufficient power.
  • Large pools or dark liners: beyond 200 lumens/m². This is where the VISION Allegro comes in, with its 5500-lumen output and advanced thermal management (thermal dimming, surge protection) to maintain stable lighting even under intensive use.

How to adapt the number of floodlights according to the liner color?

The color of the pool walls directly influences the amount of light actually perceived. Duratech specifies that the reference values (100 to 150 lm/m²) apply to pools with white or light walls. For a medium-colored liner, you must increase the luminous flux by approximately 50%. For a dark liner, which absorbs a large portion of the light, the necessary increase can reach 250% compared to the baseline value.

In practice, for a 30 m² dark liner pool, where a VISION Spectra DVM would have sufficed for a light-colored pool, it becomes preferable to opt for a VISION Allegro or to add a second floodlight to compensate for the light absorption by the liner.

Which LED configuration to choose based on pool size and shape?

Pool typeDuratech recommendation
Small rectangular pool (less than 20 m²)1 VISION Spectra DVM or DVS, 100 or 170 mm size
Standard pool (25 to 40 m²)2 VISION Spectra DVS floodlights, or 1 central VISION Allegro
Large pool or complex shape (L, eight, freeform)Several distributed VISION Allegro, with control via DuraNet
Long and narrow poolFloodlights spaced along the long sides, 170 mm size for maximum reach

Determining the right number of LED floodlights for your pool depends on several combined factors: the surface area and shape of the pool, the color of the liner, the desired atmosphere, and the level of control desired. By relying on the benchmarks of 100 to 150 lumens/m² for a light liner, and choosing from the VISION Spectra DVM, VISION Spectra DVS, or VISION Allegro models based on the power and features you are looking for, it becomes simple to design lighting that is secure, uniform, and adapted to every use. For projects requiring advanced color and intensity control, the VISION Allegro and its DuraNet ecosystem are the most complete solution in the DURAVISION range.

FAQ

How many Duratech LED floodlights for a 32 m² pool? In general, 2 to 3 floodlights are sufficient, for example, two 170 mm VISION Spectra DVS or a single VISION Allegro, depending on the desired power and the color of the liner.

What is the difference between the VISION Spectra DVM and the VISION Spectra DVS? The DVM reaches up to 1675 lumens and comes in white or RGB, while the DVS goes up to 3950 lumens and adds a Tuneable White option, for a more versatile rendering.

Can the VISION Allegro replace an old PAR56 niche? Yes, the 170 mm version of the VISION Allegro, like those of the VISION Spectra DVM and DVS, is designed as a retrofit solution for existing PAR56 niches.

Are DURAVISION floodlights compatible with salt-water pools? Yes, the entire range uses a polymer housing specifically designed to resist salt electrolysis.

Can I synchronize multiple Duratech floodlights together? Yes, with the VISION Allegro and its DuraNet technology paired with the LINK Controller and LINK Master, multiple floodlights can be automatically synchronized and controlled in color and intensity from a single control point.
