Cylindrical pendant mounted luminaire consists of housing, shade, and external louvers with complementary profiles. Heavy cast aluminum top housing with integral fitter is separated from the spun aluminum shade by four machined aluminum upper support rods, forming an aperture at the top of the luminaire. Top housing is grooved to accept one-piece EPDM gasket to provide a weather tight seal to the top of the lens. Five spun aluminum external louvers mount to the lower support rods along the length of the cylindrical clear acrylic lens. Machined aluminum lower ring anchors the support rods at the bottom of the luminaire. Lower ring with U profile closed cell silicone gasketing provides a weather-tight seal to the bottom of the lens. Cast aluminum domed bottom housing mounts to the ring with recessed socket head cap screws. Keyhole slots provide easy access for relamping. All hardware is stainless steel.

Electrical components are mounted in a conical two piece spun aluminum enclosure inside the top of the luminaire. Enclosure is finished in high reflectance white paint.
