Abstract
A deep submersible light fixture includes a substantially spherical exterior housing made of metal. The housing has a hollow interior and a first aperture extending through a front side of the housing. The first aperture communicates with the hollow interior of the housing. At least one LED is mounted inside the first aperture adjacent to the hollow interior of the housing. A transparent window extends across the first aperture. A seal is situated between a periphery of the window and the housing adjacent the first aperture for providing resistance to the entry of water into the hollow interior of the housing. An electrical connector extends through a second aperture in a rear side of the housing.
