Acuity Brands, Inc. recently introduced Lithonia Lighting D-Series Area LED luminaires integrated with Sensor Switch motion sensors. The D-Series Area Size 1 and Size 2 LED luminaires utilize motion sensors to increase energy savings in outdoor applications, saving approximately 80% in energy than comparable fixed output metal halide fixtures.
D-Series Area LED luminaires provide a modern look ideal for many commercial and municipal applications, including parking lots, plazas, campuses and streetscapes. Ideal for 15-to 30-foot mounting heights, the luminaire-mounted motion sensor provides a 15-to 20-foot coverage radius and a 300-degree coverage pattern. Innovative presets gradually dim the LED luminaire to a pre-set “low” level when the area becomes unoccupied, achieving energy savings while still providing security lighting. When motion is detected, the luminaires quickly ramp to the full output. The motion sensors feature nine fully programmable attributes including maximum output, motion time delay, dimmed level, fade down and ramp up times.
