Setup and Installation
- Unpack and Inspect: Carefully remove the string lights from the packaging. Inspect all components for any damage.
- Plan Your Layout: Determine the desired path for your string lights. Ensure the total length and number of connected strands do not exceed the maximum limits (50FT per strand, up to 20 strands total, max 432W).
- Mounting: Each bulb socket features a hanging hole for easy installation. Use cable ties, ropes, or screw nails (not included) to secure the string lights along your desired path. Ensure the lights are securely fastened to prevent sagging or damage from wind.
- Connecting Multiple Strands (Optional): If connecting multiple strands, align the end plug of one strand with the receptacle of another. Push firmly to ensure a secure, waterproof connection. Do not exceed 20 connected strands.
- Power Connection: Once installed, plug the string lights into a standard 120V outdoor-rated power outlet. Ensure the outlet is protected from direct water exposure.

Maintenance
Cleaning
Ensure the lights are unplugged before cleaning. Wipe bulbs and cords with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Bulb Replacement
If a bulb needs replacement, ensure the string lights are unplugged. Carefully unscrew the old bulb and screw in a new G40 plastic shatterproof bulb. Replacement filaments can be found by searching for B08G4N1CFS.
Troubleshooting
- Lights do not turn on:
- Check if the power plug is securely inserted into a working outlet.
- Verify that the power outlet is receiving electricity.
- Inspect the fuse in the plug. If blown, replace it with a 5A MAX fuse.
- Ensure all bulbs are securely screwed into their sockets.
- One or more bulbs are out:
- These light strands are connected in parallel. If one bulb breaks or burns out, the remaining bulbs will stay lit. Replace the faulty bulb with a new one.
- Lights flicker:
- Ensure all connections are tight, especially if multiple strands are connected.
- If using a dimmer, ensure it is compatible and functioning correctly.
