Each plastic PVC 'pixel bar' contains \u003cstrong\u003e3 RGB LEDs\u003c\/strong\u003e and a controller chip soldered to a PCB. The pixel is then 'flooded' with epoxy to make it \u003cstrong\u003ewaterproof\u003c\/strong\u003e. These are fairly large pixels but they have a lot of nice mounting options, such as two plastic flanges on the ends with 0.15\"\/4mm diameter holes and also some sticky foam tape on the back for easy attachment. They're typically used to make outdoor signs. Compared to our other LED dots, these are much bigger and much brighter, good for larger scale installations. They'd also make great large RGB 7-segment displays which is why we have them in strands of 21 not 20.\u003c\/p\u003e\n\u003cp\u003eThe pixels are connected by a \u003cstrong\u003e4-conductor cable\u003c\/strong\u003e. +12VDC, ground, data and clock.
