Why does outdoor security light not stay on for 5 minutes?

1. Incorrect Light Sensor Settings: Ensure the light sensor is set to "Dusk to Dawn" or "Auto". This setting allows the light to turn on automatically when it gets dark and turn off when it gets light.

2. Faulty Light Sensor: The light sensor might be defective, preventing it from detecting changes in ambient light. Test the sensor by covering it during the day and checking if the light turns on. If it does, replace the sensor.

3. Loose Wiring: Check the wiring connections between the light fixture, the light sensor, and the power source. Ensure all connections are secure and there are no loose wires.

4. Timer Setting: Some outdoor security lights have a built-in timer feature. Check if the timer is set to a short duration, which could cause the light to turn off sooner than desired. Adjust the timer to a longer duration (5 minutes or more) to keep the light on longer.

5. Faulty Photocell: The photocell is a small device that detects changes in light levels and controls the light's operation. If the photocell is faulty, it may not accurately detect darkness, causing the light to turn off prematurely. Replace the photocell if it's found to be defective.

6. Defective Light Fixture: If all the above checks are satisfactory, there might be an internal issue with the light fixture itself. Consider contacting the manufacturer or an electrician for further assistance.
