270 Motion sensor, 200 Watt PAR security floodlight. Precision Plus Doppler Radar combines Doppler Radar with traditional PIR (dual technology) which protects your home with improved reliability, area coverage and stable performance. Motion sensor turns lights ON automatically when motion is detected and OFF after a pre-selected time delay (1 or 12 minutes). Integral photo cell design prevents lights from turning ON with motion during daylight hours (auto modes). Universal cover plate mounts to standard recessed or surface mounted junction boxes.
