Low profile LED wall luminaire. Intended use, the versatile design of the OLWX2 LED combines a sleek, low-profile wall pack and high-output LEDs to provide an energy efficient, low maintenance LED wall pack suitable for replacing up to 400W metal halide luminaries. OLWX2 LED is ideal for outdoor applications such as building perimeters, loading areas, driveways and sign and building floodlighting. Construction rugged cast-aluminium housing with dark bronze polyester powder paint for lasting durability. Integral heat sinks optimize thermal management through conductive and convective cooling. LED's are protected behind a glass lens. Housing is sealed against moisture and environmental contaminants. Optics, high-performance LEDs behind clear glass for maximum light output. Light engines are available in nominal 4000K configurations. Electrical, light engine consists of four high-efficiency. Chip on board (COB) LED's with integrated circuit boards mounted directly to housing to maximize heat dissipation and promote long life (L76/100000 hours at 25°C). Electronic driver has a power factor of 90% and THD 20% and a minimum 2.5kV surge rating. Floodlight mounting accessories include an additional 6kV surge protection device.
