Abstract

Abstract An economical and rugged lighting fixture designed particularly for dock-side use. The fixture's major components include a funnel-shaped main housing of polyvinyl chloride having a cylindrical upper end and a cylindrical lower end of reduced diameter; a main housing extension of polyvinyl chloride having the same diameter as the lower end of said main housing and having an annular ring projecting frm its inner wall; a hollow cylindrical housing sized to fit into the upper cylindrical end of said main housing; a U-shaped fluorescent lamp; a socket for said lamp; a 120 volt transformer; a circular socket mounting bracket sized to fit snugly onto the annular ring of the main housing extension and carrying the fluorescent lamp socket and the transformer; a dished reflector surrounding the lower end of the lamp and whose outer edge is secured between the lower end of the cylindrical housing and the flared wall of the main housing; and a flat circular transparent lens bonded to the upper end of said main housing.
