Alfred,
Upon careful review of both white and bronze models, there were no mentions of a motion sensors, not in the Product Overview or the Bullets. See captions below. Our models have DUSK TO DAWN SENSORS, not motion sensors.
"The housing and diffuser are made with durable materials. Suitable for wet locations. Available in white and bronze finishes. Included are rubber sensor covers for manual operations using an on and off switch. Floodlight with dusk to dawn sensor. Built-in 18-Watt LED array. Light output is 1500 Lumens."
