Underwater Light for Concrete Pools

Underwater niche light for concrete pools. The niche is cast into the pool wall during construction and the lamp body seats inside it with cable glands and neoprene seals, so the assembly meets international safety practice for 12 V pool lighting and stays watertight for years in chlorinated water. The chemical-resistant housing takes the Waterstar 18 W, 24 W and 36 W LED bulbs in warm or cool white. Position lights on the wall facing away from the house or terrace so the beam crosses the pool rather than glaring at the viewer; one light per 25–35 m² of surface is a practical starting rule.
