I just recently purchased two of the soft flood lights to accent my water fountain. I have a number of up lights and path lights all functioning properly, However, I am not able to get these flood lights to function properly. I have made sure the LED is seated properly, I have take the flood light to a known good spot and hooked it up with no luck, I have also placed the light directly to the controller without any luck. Yes, the controller is on as I have power to the other lights when I turn it on to test these lights. Is there a special way to hook up these lights other than the directions that came with them?
