Versatile Lighting Options
- Standard Use: The lantern provides bright, diffused light suitable for general area illumination.
- Downlight Function: The lantern base includes a built-in recessed hook. This allows the lantern to be hung upside down, providing downward-directed light.
- Area Light: The globe can be removed by twisting it counter-clockwise. With the globe removed, the lantern functions as a more direct area light, increasing light output for specific tasks.

Maintenance
Cleaning and Care
To ensure the longevity and optimal performance of your UST 60-Day Duro LED Lantern, follow these care instructions:

- Storage: When storing the lantern for extended periods, remove the batteries to prevent leakage and corrosion. Store in a cool, dry place away from direct sunlight.
Troubleshooting
Common Issues and Solutions
- Lantern does not turn on:
- Check if the batteries are installed correctly with the proper polarity.
- Ensure the batteries are fresh and fully charged. Replace if necessary.
- Verify that the battery compartment cover is securely closed and locked.
- Light is dim or flickers:
