Lighting Modes
The flood light offers four distinct operating modes:
- Motion Sensing Mode (PIR): The light activates to 100% brightness when motion is detected within its range (up to 60ft and 180° angle) and turns off after a set duration (10s, 1min, 5min, 10min).
- Dusk to Dawn Mode (D2D): The light automatically turns on at dusk and off at dawn. The motion detector is inactive in this mode.

- Dim Mode: The light stays on at 20% brightness continuously at night. When motion is detected, it switches to 100% brightness and returns to 20% after the motion ceases.
- Always-On Mode: The light remains on at 100% brightness continuously, regardless of ambient light or motion.

Maintenance
Regular maintenance ensures optimal performance and longevity of your flood light.
- Cleaning: Periodically clean the light fixture and motion sensor lens with a soft, damp cloth to remove dirt and debris. Do not use abrasive cleaners or solvents.
- Connection Check: Ensure the power plug remains securely connected to the outlet and that the outlet cover (if applicable) is properly sealed to maintain IP65 waterproof rating.
- Weather Resistance: The IP65 rating ensures protection against dust and water jets. While designed for outdoor use, avoid submerging the unit.
