The wire itself is great quality — sturdy and well-insulated. I bought it to wire up several COB LED lights, but the individual wires and outer sheath were a bit too thick to fit into the press connectors I was using. It’ll work perfectly for other projects, just something to keep in mind if you’re using tight-fit connectors.

I got the TYUMEN 40FT 18 Gauge 2-Pin Red & Black Cable for hooking up LED strips, and it worked perfectly. The wire is sturdy, flexible, and easy to cut or connect, making installation quick and hassle-free. The 40-foot length is generous for longer runs, and the color-coded red and black makes it easy to keep track of positive and negative connections. Great for DIY electronics, lighting projects, or any small electrical hookup.
