4. Setup Instructions
- Plan Your Layout: Before hanging, determine the desired path for your string lights. Consider the length (100ft) and the placement of power outlets.
- Secure the Strand: Use the built-in hooks on each socket to hang the string lights. Secure the main cable first, ensuring it is taut but not overly strained. Common methods include using guide wires, hooks, or zip ties (not included) to attach to pergolas, fences, or walls.
- Install Bulbs: Once the string is securely hung, carefully screw each G40 LED bulb into its socket. Ensure bulbs are fully seated to prevent moisture entry. It is recommended to install bulbs after the string is hung to minimize breakage risk.
- Connect Multiple Strands (Optional): If you need a longer length, connect additional Arbrac string light strands end-to-end using the male and female connectors. Do not exceed a total of 8 connected strands.
- Power Connection: Plug the string lights into a standard 120V outdoor-rated electrical outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for outdoor safety.

5. Operating Instructions
- Power On/Off: Once plugged in, the lights will illuminate. Unplug to turn off.
- Dimmable Functionality: These string lights are dimmable. To utilize this feature, you will need a compatible outdoor-rated dimmer (not included). Connect the dimmer between the string light plug and the power outlet. Adjust the dimmer to achieve your desired brightness level.

- Cleaning: Disconnect power before cleaning. Wipe bulbs and cords with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.

- Weather Resistance: The lights are designed to be weatherproof (IP44). However, during extreme weather conditions (e.g., severe storms, hurricanes), it is advisable to temporarily take them down to prevent potential damage.
