6. Operating Instructions
The SZGMJIA 70W LED Barn Light features an integrated dusk-to-dawn photocell sensor for automatic operation.
- Automatic Operation: Once installed and powered, the light will automatically turn ON when ambient light levels drop (at sundown/night) and turn OFF when ambient light levels rise (at sunrise/daytime).
- No Manual Control Needed: The photocell eliminates the need for manual switching, providing energy-efficient and convenient lighting.
- Photocell Placement: Ensure the photocell sensor (small clear dome on top of the fixture) is not obstructed by objects or other light sources, as this may interfere with its proper function.

7. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your LED Barn Light.
- Cleaning: Periodically clean the lens and the photocell sensor with a soft, damp cloth to remove dirt, dust, or debris that may accumulate and affect light output or sensor functionality. Do not use abrasive cleaners.
- Inspection: Annually inspect the fixture for any signs of damage, loose connections, or wear. Ensure all mounting hardware remains tight.
- Weather Resistance: The IP65 rating ensures protection against dust and water jets. However, avoid directing high-pressure water streams directly at the fixture.
