The enemy of any Light Emitting Diode (LED) is heat. Because LEDs draw more current as they heat up, they are susceptible to "thermal runaway", where current draw heats up the diode, which draws more current, until the diode burns itself up. The LED driver,a self-contained, regulated DC power source, controls thermal runaway by maintainingconstant current. To reduce heat even more, Atlantic has moved the drivers from inside the light to the power cord, to maximize LED lifespan.
The picture below shows many Color Changing extension cords (CCEXT20) can be used, based on your total wattage for that zone. If you are needing extension cords, calculate the amount of watts of lights that you have per zone based on the below picture, you can determine how many extension cords can be used per zone.
