A bollard lighting device having a lighting unit mounted upon a tubular post to provide lighting through a 360 DEG angle in a horizontal median plane. A cylindrical lens member is captively held between a closed end cylindrically shaped upper body member and a cylindrically shaped lower body member. A cylindrically shaped inner base member fits inside the lower body member, and supports the light source which extends into the cylindrical lens. The lower body and inner base members are held together by a bayonet type lug fitting. An access door is provided in the tubular post to facilitate installation and maintenance of the wiring circuit from a power source to the light source. A lock, located in the lower body member, utilizes a cam butting against a stop to prevent activation of the bayonet type lug fitting and therefore, disassembly of the lighting unit, and access through the door to the electric circuit in the tubular post by unauthorized persons.
