Part of the Tubular family of LED luminaires, the BSS521 is an arm mounted model ideally suited for wall wash and general illumination. Aluminum arms project the Ø3-1/2” extruded aluminum housing from a wall or ceiling. A frosted acrylic lens diffuses the light from high quality diodes, while a generous range of rotation allows for flexible aiming.
