The patented dual yoke design of the Gardco Post Top luminaires is both structurally and optically motivated. It provides strength without mass, freeing the luminaire from confining supports and presenting minimum restriction to light. The yoke gives the luminaire a symmetrical, balanced appearance from all viewing angles Engineering detail is elegant throughout, making the luminaires durable, weatherproof and easy to install, service and maintain without compromising the visual appeal. With two housing diameters available - 17" and 22"; Gardco's Post Tops are designed to be applied at mounting heights between 10 to 25 feet, making them equally appropriate in both landscape and area applications. The CP luminaires accept lamps up to 1000w.
