ABSTRACT:
A watertight lamp fixture which is especially adapted for use on offshore oil rigs and other installations where lamps are exposed to severe weather conditions. The fixture is provided with a quick opening and closing latching system to allow workmen to replace bulbs and perform other, similar maintenance in a minimum of time while working under inclement and often dangerous conditions. Additionally, the lamp cover is attached to the body of the lamp in a manner which insures a positive seal between the cover and body of the lamp fixture when the cover is latched in place.
