Pioneers in underwater lighting

Over the past three decades, we have remained dedicated to setting the industry standard, providing innovative lighting solutions trusted by leading shipyards and yacht owners worldwide.
Customer Feedback
Innovation Rooted in Expertise
With over 30 years of experience, we specialise in high-performance lighting solutions for both new builds and retrofit projects. Our seamless LED upgrades enable existing fixtures to be enhanced without requiring haul-outs, hull modifications, or class certification changes. This unique approach ensures that our solutions save time and money, offering superior results with minimal disruption.
A Range Built to Last
Our commitment to quality and precision sets us apart from the competition. Unlike competitors who produce dozens of models that are often discontinued, we focus on a select range of meticulously engineered lights. This deliberate approach ensures that every product we manufacture is built to last, saving our clients the cost and inconvenience of replacing outdated or unsupported models.
Our lights are not only crafted to deliver powerful performance but also to provide long-term reliability. In fact, the very first superyacht fitted with our lights in 1991 still has them in perfect working order today. This testament to our build quality is why our clients trust us time and time again.
Quality Manufacturing, Fully Controlled
Our manufacturing process is entirely in-house, handled at our purpose-built 5,000 sq ft facility in the UK. Unlike competitors who outsource production, we maintain complete oversight of every stage, from design to assembly, ensuring exceptional quality and rapid turnaround times.
We use only LRS 3.2-certified materials and adhere to the stringent requirements of classification societies such as Lloyd’s Register, RINA, ABS, and DNV. This dedication to quality means our lights meet the highest standards of safety, durability, and performance.
Engineered for Performance
Our lights are designed to excel in the harshest marine environments, delivering energy- efficient, reliable illumination for years to come. With a select range of thru-hull, weld-in, and flush-fit models, we focus on engineering fixtures that offer unrivalled performance and longevity, trusted by shipyards, yacht builders, and owners worldwide.
