unfortunately did not burn all LEDs in a luminaire. Have everything sent back and get the money back. In order again I have the set twice ordered and paid for, but is only one set arrived with me. Reportedly a computer error at the merchants. After several phone calls to the dealer me then the missing kit was sent after 14 days. Of course it was not what I had ordered. The first pond lighting has a twilight switch and cool white LEDs, as well as ordered and delivered subsequently set had no twilight switch and warm white LEDs. I have the lights installed in the pond under water, yet all are tight.
