Adafruit NeoPixel LED Side Light Strip - Black 60 LEDs, this is the version of our Side Light strips with 60 LEDs per meter.
The strip is made of flexible black PCB material with a weather-resistant casing. You can easily cut this material with wire cutters. There's a cut line in the middle of the strip. Solder to the 0.1" copper pads and you're ready to go! Of course, you can connect them together to make them longer, just watch how much current you need!
These strips come in 1-meter reels, with a 2-pin JST SM connector at each end.
