25 years ago we made the very first underwater light for a ground breaking Superyacht in Europe. A quarter of a century later those same lights are still working perfectly and is testament to our ability in making the best products in the market. We've NEVER had a light fail due to water ingress. We have kept our overheads low and our team small in order to stay efficient and competitive and that's why we are amongst the small number of trusted companies in the industry.

All of our products are designed and made in house. We use local specialized sub contractors when needed and have and never will 'farm' our production or design out to companies in China or Asia. We believe in first principles and are not willing to cut corners in order to save a dollars. 

All of our products are made from the very highest grade Aluminum, Bronze and 316L Stainless steel. Not only is this essential for strength and longevity but aids heat dissipation and structural strength. Although plastic housings offer a vastly reduced cost benefit, this saving is not in the customers best interest and therefore not in ours.
