LED underwater light 2 pieces - 18W - Cool white 4000K - 1,620 lm - 24V AC/DC (power supply not included) - IP68 - stainless steel 304 - Ø190mm - pond & fountain

Set of 2 LED underwater lights of 18W, each delivering 1,620 lumens in bright cool white 4000K. The light, base and bracket are made of stainless steel (grade 304) and the lights are waterproof to IP68 up to 3 metres deep. Ideal for beautifully lighting up a pond, fountain, waterfall or water feature in the evening.

Please note: these underwater lights run on 24 volts. A 24V power supply is NOT included and must be purchased separately. Never connect the lights directly to 230V; they will be destroyed instantly, and under water this is life-threatening. For this set of 2 you need a 24V power supply of at least 45W.

What's in the box, and what isn't?

• ✔ 2 × LED underwater light 18W with base, tilting bracket, built-in LED driver and moulded connection cable
• ✘ No 24V power supply (order separately)
• ✘ No extension cable, junction box or waterproof connectors

How to connect the underwater lights

The lights run on 24V AC or 24V DC. The wiring is always: 230V → 24V power supply → underwater lights. Connect both lights in parallel to the 24V output of the power supply: brown = positive (+), blue = negative (−).

• Power supply rating: 2 × 18W = 36W. Allow at least 20% headroom, so a power supply of 45W or more.
• Always keep the power supply above and out of the water. Install it somewhere dry or, outdoors, choose a waterproof power supply (IP67) placed well away from the water's edge.
• Connections: preferably make connections above water, in a waterproof junction box. If a connection has to be under water or in the ground after all, use an IP68 connector.
• Long cable runs? At 24V, the voltage drops over long distances. For cable runs of more than 10 metres, use a thicker cable (for example 2 × 1.5 mm²).

Not sure about the wiring? Then have it done by an electrician.

Placement in 4 steps

1. Choose the spot on the bottom of the pond or fountain, no more than 3 metres deep. The light is Ø190 mm and 220 mm high including the base.
2. Stand the light on a firm, level surface, such as a paving slab or stone. You can also screw it down through the holes in the base.
3. Aim the light using the bracket: it tilts 180° up and down and rotates 360°. Point it at the fountain jet, the waterfall or the plants.
4. Run the cable to the edge, make the connection to the 24V power supply above water and check that all lights come on.

Built for under water

The lights have been tested to the European standard for luminaires for swimming pools and similar applications (EN 60598-2-18) and are waterproof to IP68 up to 3 metres deep. The light surface is covered with tempered glass with a rubber sealing ring, the driver is potted watertight, and the light, base, bracket and screws are made of stainless steel 304. If you use them in a swimming pool, always have the installation carried out by a qualified electrician, with a safety transformer.

What light effect do you get?

Each light delivers 1,620 lumens in cool white 4000K: fresh, bright light that makes water look extra clear and lively. The 30° beam angle gives a narrow, focused beam that reaches far, even through water, ideal for lighting a fountain jet or waterfall from below (see the light simulation). The clearer the water, the better the effect. This wattage is ideal for medium-sized ponds, fountains and waterfalls, and for lighting up waterside planting.
