4. Setup and Installation
Follow these steps for proper setup and installation:
- Unpack and Inspect: Carefully remove the string lights from the packaging. Uncoil the string and inspect all bulbs, wires, and plugs for any signs of damage. Do not plug in if any damage is found.
- Plan Placement: Determine the desired location for your string lights. Consider the length (4.9 m / 16 ft) and the proximity to a 120 V power outlet.
- Connecting Multiple Sets: These string lights are designed to connect multiple sets end-to-end. Locate the male plug on one end and the female receptacle on the other. Connect the male plug of one set into the female receptacle of another. Remember the limit of 36 sets per outlet.
- Mounting: Use appropriate installation hardware (e.g., clips, hooks, or zip ties) to secure the string lights. Ensure the lights are hung securely and the wire is not strained or pinched. Avoid hanging the lights in a way that could cause tripping hazards.
- Power Connection: Once securely installed, plug the string lights into a standard 120 V electrical outlet.
Installation Planning Guide
Refer to the following guidelines for estimating the number of lights needed for common applications:

Figure 3: Installation planning guide for various applications.
- Traditional Shaped Tree: For C9 bulbs, approximately 25 lights per foot of tree height.
- Roofline: A general rule is 16 feet for a standard single car garage and an additional 10-12 feet per awning.
- Railing: Measure the length end-to-end of the railing. For a standard railing, consider purchasing double the measured length to allow for wrapping.
