Love these lights! The lights are made of glass and a lightweight metal. The quality is there, not cheap. Easy to turn on and set up. You can can set the lights to one color, but I prefer the changing to different colors. They go on at dusk and seem to stay on well into the evening at least until 1 am but maybe even later. (I haven't been up to see them on later.) You won't be disappointed. Highly recommend.
