Description
Underwater lighting with character
The SUW-18W delivers a high 1620 lm for large water surfaces. It evenly illuminates expansive ponds and pools and shows off large fountains and water features impressively.
When the sun goes down, your garden turns into an atmospheric backdrop: the water glows from within, fountains and water courses sparkle and cast lively reflections all around. An ordinary garden becomes an inviting retreat for relaxing and unwinding. The even, neutral-white light beautifully stages the textures and movement of the water. Balmy evenings on the terrace take on a whole new atmosphere – elegant, calming and simply beautiful.

Connection & safety
The spotlight runs on DC 24 V (V+ brown, V- blue) and needs a suitable 24 V power supply or transformer (available separately). Important: never connect to 230 V or any voltage higher than 24 V – this will destroy the luminaire. Installation and maintenance should be carried out by a qualified person.
Applications
Ideal for large garden ponds, swimming ponds, pools and larger fountains. Several units create impressive, large-area lighting effects.
