The picture is a false advertisement. I purchased one and set it up on the other side of my pool. ahhh about 25 feet away. Was hoping that we were going to be able to see the lites at least  at dusk. Wrong.. If ya wanna get up at 2am and look VERY close you may see the lites.. And, as I understand they cannot be changed.  Im sorry that I spent the $400.00 or so.
