Should Motion Sensors be Used with LED Task Lights?
Since most LED task lights operate at under 13W, the benefit of using a motion sensor does not necessarily outweigh the additional cost. In addition, motion sensors provide an “active” power draw which decreases the overall efficiency of the product. The motion sensor also provides one more complicated component which can fail and, if it is hard-wired into the fixture, can require replacement of the entire fixture if it fails.
