Abstract
Improved projector for underwater lighting, which is characterized by comprising two parts that are coupled and fixed to each other, determining, between both, a cooling chamber and cable reserve electrical conductors; one of these parts is made up of a hollowed-out casing that can be recessed in the installation site, fitted with a cable outlet with threaded inner cable gland and an external tube to be connected to the cable conduit, thus avoiding the possibility of water filtration. The cooling chamber through the pipes of the electrical pipeline. (Machine-translation by Google Translate, not legally binding)
