LED strip segments can be joined using solderless connectors. These connectors simply slip onto the ends of the LED strip and require no tools or equipment.
LED Strip to Strip
These connectors have plastic connector pieces on both ends. Use these to connect two LED strip segments together.
LED Strip to Wire
These connectors have a plastic connector on one end only. The other end is bare wire. Use these to connect the end of an LED strip to power supplies and other devices.
