Abstract: A housing, particularly for a Light Emitting Diode (LED) or otherwise lamped in-grade or under-water light fixture, is made of ceramic material, such that the housing is not affected by corrosive substances commonly found in soil, masonry, and water that surrounds the installed fixture. The ceramic housing establishes a good conductor of heat and does not conduct electricity. A lens and lens frame are secured to the housing and provisions are made to assure the integrity of the overall assembly even when the light fixture is employed in damp and wet environments and/or where heavy loads can bear down on the lens, such as when the light fixture is embedded in a paved roadway and subjected to vehicular traffic rolling there over.
