4 ft 65 W 120 to 347 V Tri Level Motion Sensor LED Strip with 40 K and bridge normally on emergency remote. The S20LV series LED strip lights feature an integrated tri-level microwave motion sensor that regulates light levels according to the occupancy of a space. These luminaries have been specially designed to prevent energy loss and to increase energy savings, by allowing the end-user to sensibly manage the degree of luminosity in applications or spaces that require continuous lighting, such hallways and common areas.
