Installation

The UT-SP mounts to the pool wall with screws. Before installation, have the installer check the wall surface, mounting points, and cable exit position against the instructions for the specific model.

Use 12 V DC only. Have a qualified electrician install the light in accordance with the product manual and applicable pool electrical requirements. Never connect the fixture directly to mains power.

Light Color Options

Warm WhiteWarm white, approx. 3000 K

Cool WhiteCool white, approx. 6000 K

RGBWColor-changing light + dedicated white

How do I choose a light color? Cool White (CW) gives water a clear look in blue-tiled pools. Warm White (WW) creates a warmer look against sand or gray tiles. RGB or RGBW lets villas and resorts vary the lighting to suit the occasion.

Pool Size and Lighting Guide

General guidelines for residential pools 1.21.5 m deep. Deeper pools, darker tiles, or higher brightness requirements may call for higher-wattage fixtures or more lights.

Pool TypeWater Surface AreaNumber of LightsPower per Light
Spas / Hot Tubs / Steps 12 lights612W
Small Pool, 3 × 6 mApprox. 18 m²12 lights1825W
Residential Pool, 4 × 8 mApprox. 32 m²23 lights1835W
Residential Pool, 5 × 10 mApprox. 50 m²34 lights2535W
Large / Hotel Pool, 6 × 12 m and up72 m² and up46 lights or more3545W

The UT-SP models listed on this page are available in 6 W, 12 W, and 18 W. Typical spacing is 34 m, with the lights installed approximately 4560 cm below the waterline. Aim the lights away from the main viewing area, such as the house, to reduce glare.

Care and Maintenance

  • Switch off the light and its circuit breaker before cleaning or removing the fixture.
  • Wipe the lens monthly with a soft cloth or sponge to remove scale and algae that can reduce light output.
  • Maintain balanced pool water (pH 7.27.6) to help reduce scale on the lens and extend seal life.
  • Inspect cable junction boxes and connections once or twice a year for moisture, standing water, or corrosion.
  • Limit out-of-water testing to 12 minutes. The fixture is designed to dissipate heat through the surrounding water.
  • Avoid wire brushes and strong acids on the stainless steel trim. Use a mild stainless steel cleaner for stains.

Frequently Asked Questions (FAQ)

Can I use my existing 12 V AC transformer with the UT-SP?

The UT-SP requires a waterproof 12 V DC driver (DY series). Connecting it to an AC transformer can damage the fixture, and the warranty excludes damage caused by an incorrect power supply.

What is the difference between RGBW and RGB?

RGB combines red, green, and blue to produce a white light that can have a bluish tint. RGBW adds a dedicated white LED, so you can use white light for everyday swimming and switch to colors when desired.

Which model should I choose for a saltwater pool, UT-SP or UT-AP?

The UT-SP is recommended for saltwater or coastal pools because its 316 stainless steel trim resists corrosion and has a polished finish. The UT-AP uses rust-free ABS and has a simpler finish.

How much energy can LED pool lights save compared with halogen?

As a general comparison, 1835 W LED fixtures can offer light output comparable to 100300 W PAR56 halogen lamps, with potential energy savings of about 8090%. The stated LED service life is more than 50,000 hours.

Can I install the light myself?

Have a qualified electrician or experienced pool technician handle the wiring, power supply, and residual-current protection. WinWin Pool offers installation services in Bangkok, Hua Hin, and Pattaya.

How long is the warranty?

The featured products on this page carry a two-year warranty, subject to company terms. The warranty excludes damage caused by an incorrect power supply or voltage.
