Specifications:
The document outlines the requirements for lighting systems used in marine environments, specifically for the ferry 'Le Normandie' operated by Brittany Ferries. Key specifications include absolute and durable imperviousness, even after multiple lamp changes, and the use of materials with high resistance to corrosion such as polycarbonate, glass, and 316L stainless steel. The lighting systems must also resist vibrations and mechanical shocks.

Installation Features:
The lighting systems are designed for easy installation, featuring variable attachment centre distances and the capability for 360° orientation of the luminaire.

Applications:
The lighting solutions are intended for use in marine environments, particularly on ships, where durability and resistance to harsh conditions are critical.
