For larger floor lamps or higher wattage, consider 16 AWG.
Wire Type:
SPT-1: Thinner insulation, more flexible, ideal for table lamps.
SPT-2: Thicker insulation, better durability, suitable for floor lamps.
Cord Style:
Standard clear or black PVC cords.
Braided fabric cords for a vintage look.
Cords with built-in switches or dimmers for convenience.
👉 If you’re unsure, an 18 AWG SPT-2 replacement lamp cord with plug is the most versatile choice.

Step-by-Step: How to Replace a Lamp Cord
Step 1: Unplug and Disassemble the Lamp
Always unplug the lamp before working. Remove the lampshade and bulb, then access the socket by unscrewing it from the base.
Step 2: Remove the Old Cord
Locate where the cord enters the socket terminals. Unscrew the connections and carefully pull out the old cord through the lamp body.
Step 3: Prepare the New Cord
Measure the length you need.
Strip about 1/2 inch (12 mm) of insulation from each conductor.
If using a cord with a plug, skip attaching one manually.
Step 4: Connect the Wires to the Socket
Identify the neutral (ribbed insulation) and hot (smooth insulation) conductors.
Attach the neutral wire to the silver screw terminal.
Attach the hot wire to the brass screw terminal.
Tighten screws securely.
Step 5: Reassemble the Lamp
Feed the cord back through the lamp body, reattach the socket, and secure all parts.
Step 6: Test the Lamp
Insert a bulb, plug in the lamp, and turn it on. If everything works, your lamp is safely rewired!
