| Motion sensor not working. | Too much ambient light; Sensor obstructed; Motion outside detection range. | Ensure installation in a dark area; Clear any obstructions from the sensor; Adjust light position for optimal detection. |
| Light turns off too quickly. | Standard auto-off time (15 seconds). | This is normal behavior for motion sensor mode. For continuous light, use Always-On mode. |
