Why does my motion sensor exterior ceiling light stay on?

Why does my motion sensor exterior ceiling light stay on? 51lighting does not list a ceiling light with a measured motion-sensor range. Do not assume a detection distance or an IP number that the product page does not print. A sensor that turns on by itself is often seeing movement, headlights, or a sensitivity set too high. A light that stays on is often in test mode or the sensor is stuck. For a porch, use a fixture whose page states a damp or wet rating.

How to decide

• Match the room: flush mount on an 8 foot ceiling, pendant or chandelier only where people will not hit it.
• Read lumens, kelvin, and dimming on the product page. Do not invent a rating the page does not show.
• Confirm any minimum order before you add the item to a wholesale cart.
• If the ceiling box is loose, cracked, or not rated for the fixture, hire an electrician.

Fixtures to compare on 51lighting
