The Great Dunton Forge
At Underwater Lights Limited, we believe that exceptional products start with exceptional craftsmanship. That’s why we design, engineer, and manufacture every light in our purpose-built 5,000 sq ft UK facility. Unlike many competitors who outsource production, we maintain full control over every step of the process, from concept to completion.
Our in-house team of engineers and technicians brings decades of expertise to every project, ensuring that each light meets the highest standards of performance, durability, and quality. By keeping manufacturing in-house, we can offer bespoke solutions with faster turnaround times, allowing us to adapt quickly to the unique requirements of yacht builders and owners.
