    That's kind of silly, controlling by latitude and longitude.

    Basically, you want the lights to come on when it's dark, and turn off when it's light, right?

    My guess is that it calculates sun rise and sunset throughout the year based on Latitude and the time of day programmed in buy the user. I suppose it could have a GPS receiver that loads information that automatically.
