Presence Sensor Bulkhead Light- Energy Efficiency in an Innovative Design-This is the advanced sensor light for energy efficiency, combined with convenience. This is through its advanced presence sensor that auto-senses movement. Therefore, instantly it illuminates in case it detects movement, a great solution in making places residential, commercial, or industrial safe and secure. If placed in halls, stairways, outdoors, or at door entrances, these lights will have spaces lit when they are supposed to be well-lit and therefore do not unnecessarily waste energy.
