Description
Underwater lighting with character
The SUW-3W is the most compact version of our underwater spotlights and sets targeted light accents under water. With just 3 W and a narrow 30° beam it highlights individual details – such as water jets, plants or small figures. Thanks to its small size (Ø 82 mm) it can be placed discreetly even in tight spots.
As dusk falls, your garden begins to glow: the water shimmers in warm, clear light and gentle reflections dance across the surface. Where there was only a quiet pond by day, a small oasis of light appears in the evening, inviting you to linger. Plants, stones and water features stand out vividly and take on an almost magical depth. Even the smallest garden pond becomes the atmospheric centrepiece of balmy summer evenings – a sight to enjoy anew every night.

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 small garden ponds, table and ornamental fountains, aquariums, water bowls and decorative water features. The tiltable stainless steel base lets you aim the beam precisely at the desired detail.
