These are NOT motion detection lights, just light detection (from dawn to dusk). If you read the fine print it doesn't claim to detect motion only from "dawn to dusk" and "auto on/off" BUT Revain's search will show them when looking for LED lights "motion sensor" and/or " Motion detectorโ is searched for . I'm not sure if Revain or the seller is responsible for the errors in the search results. Otherwise the bulbs seem to work fine, maybe not as bright as a 100 watt bulb but not bad.
