This spotlight body ( 1 ) and the transparent front ( 2 ) are made of plastic material and the printed circuit ( 6 ) including the LED's ( 5 ) is arranged in a juxtaposed arrangement on a metal plate ( 4 ) being fit to dissipate the heat being produced by the LED's, the metal plate being cooled by the water flowing into the body ( 1 ) of the spotlight through lateral openings ( 8 ) being provided in the body. The body ( 1 ) is concavely shaped and has the dissipator plate ( 4 ) securely attached to it at its open front end, the body ( 1 ) having at its center an inner pillar having a hollowed-out portion ( 10 ) and an outer open end ( 11 ) to receive the spotlight's electric connections ( 13 and 14 ) that will be fitted to it.
