Bersub has been illuminating underwater life since 1988

Bersub is a leading French company in the field of underwater lighting.. Since our establishment in 1988, we have been committed to providing high-quality products to meet the needs of professional and amateur divers. Through our expertise and passion for innovation, we have developed a range of underwater diving torches that are renowned for their exceptional reliability, performance, and durability.

 

Our commitment to quality is reflected in the partnerships we have established with organisations such as the French Navy, Gendarmerie, SDIS, CNRS and IFREMER, who use our products in their most critical missions. We are proud to contribute to their success by providing them with reliable, high-performance underwater lighting.

Innovation at the service of passion

At Bersub, we believe that innovation is the key to our success. We are constantly looking for new technologies to improve the quality of our products and meet the needs of our most demanding customers. We also work closely with professional and amateur divers to understand their needs and expectations, so that we can offer products that perfectly meet their requirements.

In our workshops at Saint Genix sur Guiers in Savoie, we manufacture both off-the-shelf products and custom-made prototypes for all types of diving (Explo, Photo, Video, Tek...), ROVs... but also for specific lighting installations (caves, fountains, pools...), as well as specific products concerning user safety with the production of lifelines.

Bersub lighting is designed and manufactured in France to guarantee a product of excellence and a 10-year spare parts service.

We use the best materials and components to ensure that our products perform and last.

Our commitment to our customers doesn't end with the quality of our products. We're proud to offer a first-class after-sales service, with a dedicated team on hand to answer any questions or concerns. We believe that our focus on quality, innovation and service is the key to our continued success, and we look forward to helping you find the right product for your underwater lighting needs.
