Underwater Light with Niche
Pool: Liner
Available options
Product Code: UWL-1-L
Category: Lights
Made in two versions: for concrete pools and for liner pools. Underwater niche light for liner (vinyl) pools. The niche clamps the liner between a flanged body and a gasketed front ring, so the membrane stays watertight around the opening, and the lamp seats inside with cable glands and neoprene seals to international safety practice for 12 V pool lighting. The chemical-resistant housing takes the Waterstar 18 W, 24 W and 36 W LED bulbs in warm or cool white. Cut the liner only after the niche is fixed and the pool is part-filled, and run the lamp from an isolating safety transformer sized for the total load.

Frequently asked questions
Niche light or nicheless light?
The niche light (UWL-1 for concrete, UWL-1-L for liner pools) seats in a housing cast into the wall during construction and gives the classic recessed look; it takes the 18, 24 and 36 W LED bulbs. The nicheless range (LL-18, LL-24, LL-36) mounts flat on the wall with no recess, which makes it the fastest fitting for new builds and the simplest retrofit.
What voltage do the lights run on?
12–14 V AC only, fed from a safety isolating transformer in the plant room — never directly from the 220 V mains. The transformer provides galvanic separation between the mains and the water, and the fittings are sealed to IP68 for continuous submersion. Keep cable runs short to limit voltage drop.
18 W, 24 W or 36 W?
18 W for spas and small plunge pools, 24 W as the standard fitting for residential pools, 36 W where the pool is wide or deep and each fitting has to cover more water. Space the lights evenly along one wall, aimed away from the main viewing angle, for level illumination without glare. Warm white and cool white are both available.
How many lights can one transformer carry?
The 200 W safety isolating transformer carries five 36 W or eleven 18 W lamps at the arithmetic limit; specify it to about 80 per cent of its rating — four 36 W or eight 18 W — so the lamps see full voltage. Connect each light through a waterproof junction box above the waterline.
