You could use a simple switch between the RC+ and RC-. Open the switch and the LEDs turn on. Close the switch and the LEDs turn off and the LED driver draws less than 0.5 Watts stand-by power. Look for the word FUNCTION on the left side of the data sheet to see the brief RC info.
RC+ could be connected to a microprocessor output pin pulled hi for lights on and pulled low for lights off. RC- must be connected to the common pin of the microprocessor.
