RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each metal 'pixel square' contains 4 RGB LEDs and a controller chip soldered to a PCB. The pixel is then 'flooded' with epoxy to make it waterproof. These are fairly large pixels but they have a lot of nice mounting options, such as two metal flanges on the side and a 0.15"/4mm diameter hole in the middle so you can screw them directly onto a surface. 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.
