OceanLED M3118w is a high performance, lightweight Colours LED underwater light for the Superyacht market.

The M3118w is a perfect choice for new build or retrofit projects and outputs up to a truly impressive 8400 lumens. The RGBW LEDs can be controlled using smartphones or tablets via WiFi.

The M Series benefits from bespoke optics that control the output of light into an elliptical beam, giving a much more defined spread and penetration through the water than most other underwater LED lights.



3 cofferdams (0°, 5°-30°, 35°-50°) make it simple to specify. Optional rear cofferdam for fitting in a tank. Rear cofferdam fully encloses the light body ensuring no galvanic corrosion.

OceanLED Colours Superyacht underwater lights provide the ability to create any desired colour scene for your yacht.

Choose from a limitless colour palette to best suit the yachts ambience and maximise the lighting effect in varying water conditions, or enhance a party theme/atmosphere or simply change the colour for fun!
