Each pixel contains three 5050 RGB LEDs along with a dedicated WS2801 controller chip. All of the LEDs are controlled at once so you cannot have one pixel with the three LEDs different colors. (Color control is per single rectangular 3-LED pixel only) The total max brightness of all LEDs is about 4500mcd.
This RGB pixel strand is connected by a 4-conductor cable. Data is shifted down from one pixel to the next so that you can easily cut the strand or attach more onto the end. The four connection wires carry the following signals: +12V , Gnd , Data and Clock .
Pixels are digitally controlled, with an internal 8-bit PWM LED driver (24-bit color for 16 million different shades). Pixels must be clocked by a microcontroller, or other control devices. There are many examples around the web available showing simple connections and code for the Arduino as well as other microcontrollers.
