Abstract
A submersible lamp having a housing and a lens with a bulb carried therein in optical alignment with the lens. A pair of terminal connections are provided for electrically coupling the bulb to a source of illuminating energy. The housing forms an open air chamber to define a volume of air such that upon submersion of the housing in water, the air is compressed to create a force sufficient to prevent the water from rising within the housing above a pre-determined level into contact with the bulb and terminal connections.
