No warranty because I had to take it apart to split up the 'moon light' LEDs from the white LEDs. From the factory it's one power source and you can set the toggle switch to different settings but this does you no good if you run a timer, which I do. So I took it apart and split up the two circuits and made it so that each circuit has it's own power source which I have plugged into offsetting timers. I think the newer versions have a timer built in but I'm not sure if it allows you to run them both on offsetting timers or not. Either way I checked all my world and all my solder joints are still fine so I suspect a faulty power source component (capacitor most likely) that's not energizing properly upon power up. At any rate, I have no warrant so I'm left with this turd that I overpaid for and due to my experience I can't recommend this product nor will I buy another one if it does finally go out for good.
