Query: Don't waste your money

I purchased these Malibu lights a few months ago. They don't work well. First of all, some of them come on before it's dark during what I'd call a very light twilight. Secondly, if you live in an area that is cloudy a lot like I do, the lights only seem to gather enough charge to be on for maybe 2 hours. So, combined with the first problem, it means the lights are on during twilight and not on when it is actually dark. Don't waste your money.
