Set for one week for light by night a place of outer passage. Perfect operation: this projector is charging in the light, not just the sun, detects the presence of side to 3 meters, but face to 4 or 5 meters, lights (a cool white) up to 6 meters with sufficient power for a crossing, autonomy seems very important since it clarifies that when it detects a presence and it is night, the seal is perfect (after 3 days of rain), in short, a small object affordable which is very useful and reliable ... I bought a 2nd.
