Tortuga outdoor wall light in bulkhead light design made of brass and glass High-quality brass and clear glass with a prismatic structure - these are the materials used to manufacture the Tortuga wall light in Italy. This choice of material makes the light resistant to seawater and therefore ideal for use in coastal regions. Designed in the classic and maritime form of a bulkhead light, the outdoor wall light fits particularly well in a rustic maritime environment, whether mounted on a wall or on the ceiling.
