If you're installing multiple strip lights and are looking for a quick way to combine them, these 12-volt LED strip light barrel plug connectors could be the ideal solution.
Generally used to connect power to small projects, barrel plug connectors are discreet, making them an ideal alternative to electrical tape, soldering irons, splicing, and crimping when making numerous connections - only a small screwdriver is needed!
Please note that this barrel plug connecter only mates with 5.5 x 2.1 mm barrel jacks but can be used to pair lead wires for connection from a power supply or cable.
