LED spherical light fixtures with enhanced heat dissipation

A submersible light fixture, comprising:

• a partially spherical housing made of metal and having a hollow interior and a first aperture extending through a front side of the housing;
• a transparent window extending across the first aperture;
• a seal between a periphery of the window and the housing for providing resistance to the entry of water into the hollow interior of the housing;
• at least one LED mounted inside a cavity formed by at least one exterior surface of the housing and a rear side of the window;
• and an electrical connector extending through a second aperture in a rear side of the housing;
• wherein the housing includes a front partially hemispherical body and a rear partially hemispherical body that are mated together.
