Features
The BSW511 is a wet location, arm mounted LED luminaire, ideally suited for wall wash and facade lighting. Slender aluminum arms project the Ø2-1/4” 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. Each fixture is paired with a remote mounted, wet location 0-10V dimming or non-dimming driver and housing.
