How long is the cord for the Easy Plant LED light? Why is the cord so long?

The cord length on all of models of the Aquarium Co-Op Easy Plant LED is 12 feet. The cord length between the light and the controller is 3 feet. We developed this product to have a long cord so that customers can utilize this on aquariums that may be located far from a power source. Additionally, we didn’t want the light to have a heavy ballast hanging off the back of the aquarium, potentially dragging the light down, so we designed the electrical ballast to be built into the plug itself.
