This is my 2011 RGB Christmas light show in Albion Park NSW Australia. The display is 5000 channels of individual control being sequenced and run by LightShow Pro V2 software.
All the lights are RGB (Red, Green, Blue) running from either 12vdc or 5vdc power supply. The RGB colour enables the whole display to be able to change to any colour in a beat and to allow for a flowing rainbow effect across the whole house
