Acuity Lithonia D-Series area LED luminaires with motion sensors
By Anthony Capkun
March 28, 2013 – Acuity Brands Inc. unveiled Lithonia Lighting D-Series area LED luminaires integrated with Sensor Switch motion sensors. The D-Series Area Size 1 and Size 2 luminaires employ these sensors to increase energy savings in outdoor applications, saving about 80% in energy, says Acuity, than comparable fixed-output metal halide fixtures. Suitable for 15-ft to 30-ft mounting heights, the luminaire-mounted motion sensor provides a 15-ft to 20-ft coverage radius and a 300º coverage pattern. Presets gradually dim the 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 up to full output. The motion sensors feature nine fully programmable attributes, including maximum output, motion time delay, dimmed level, fade down and ramp up times.
